I have no idea, nor do I know why Burda broke out into song either–how much do you have to love a media mogul willing to do that?

But I got it all on video and a whole lot more on the last day of the pre-Davos European gathering focused on digital issues and innovation.

(And here is a post by European serial entrepreneur Martin Varsavsky, who apparently thinks his video shows that Accel Partners’ Simon Levene and I were not impressed enough by Campbell.)

In any case, DLD’s motto was: “Uploading the 21st Century.” And while it did not quite do that, there were definitely a lot of interesting moments I captured for your viewing pleasure.

Along with Campbell (who was supposed to appear on a panel on Africa, but did not) and a singing Burda, the video features clips from two sessions today.

The first was titled “Exploding Media” and included: pundit Clay Shirky riffing on flash mobs; a very funny clip of kids talking about television (made by Technorati’s Peter Hirshberg); Google’s Marissa Mayer noting that Google will still not be in the content business; Yahoo’s Bradley Horowitz discussing Yahoo’s plans to de-focus on making original content; and BuzzMachine blogger Jeff Jarvis advising old media to just ask WWGD? (What would Google do?).

Another session on the video features the founders of the genetics-focused social-networking company 23andMe–Anne Wojcicki, Linda Avey and Esther Dyson–answering questions about fears people have about learning too much about DNA.

Here is the video (and now I am off to Hamburg to visit Xing, a business social-networking company):

I am now at the DLD conference in Munich, which is put on by Hubert Burda Media, a gathering that has become one of Europe’s most interesting in recent years.

The three-day DLD–which stands for Digital, Life, Design–focuses on digital innovation, science and culture and has the most cosmopolitan audience of any conference out there.

It is chaired by publisher Hubert Burda and serial Israeli investor Joseph Vardi and hosted by Stephanie Czerny and Marcel Reichart.

It is interesting to be here to garner a lot of different viewpoints from outside the U.S., and I will be visiting a lot of German Web start-ups over the next week.

There is also a lot of Olympic-level schmoozing, of course, since there are precious few such events in Europe compared to the conference-crazy U.S.

There are also, of course, a lot of the usual suspects from the States and especially Silicon Valley.

So far this morning, I have run into folks like former Microsoftie Linda Stone, Yahoo’s Bradley Horowitz, writer and entrepreneur Esther Dyson, Facebook’s Matt Cohler and, yes, Martha Stewart (who needs no introduction).

I am also here to interview onstage for DLD today Kenneth Roth (pictured here), longtime executive director of Human Rights Watch, which investigates, reports on and seeks to curb human-rights abuses in some 70 countries.

To say I am out of my league in interviewing such a serious and substantive figure is an understatement, especially given that I spend all my time contemplating the monetization of widgets (to be more specific, the non-monetization), the fate of content on the Web and the exact date the hype of social networking will end.

Still, I will give it my best effort and perhaps focus on the use of digital tools to get information and stories of heinous injustices out worldwide. After all, the Web has to be more than SuperPoking and dumb online videos on cats skateboarding.

Our session is aptly named: “Inconvenient Stories.”

My favorite kind.

Video, of course, to follow.

How glad BoomTown was to finally see Jerry Yang up close and personal, after our valiant but futile efforts to get near the Yahoo co-founder and CEO in 2007.

No, we’re not stalking him in a restraining-order kind of way, although I did stake a claim to a front-row seat in the intimate theater at the Las Vegas Hilton for his keynote this morning at the Consumer Electronics Show, where Yang couldn’t help but see me.

Like he cared!

Not at all, as he was riveted to delivering his shtick about Yahoo’s mobile efforts (it’s a 3.0 version, according to Yang, which is a good move since Web 2.0–in general and in particular–has not been so kind to the Internet giant), as well as giving the audience a glimpse of some interesting new concepts related to its popular email program.

The front rows were so packed with top Yahoo execs–including President Sue Decker, as well as David Filo, Jeff Weiner, Brad Garlinghouse, Ash Patel, Dave Karnstedt, Bradley Horowitz, Hilary Schneider and even Chairman and former Yahoo CEO Terry Semel–that you had to wonder who was running the show back in Sunnyvale, Calif.

(I mean, say, if Google had decided to launch a sneak attack today with their bicycle brigade, it could have taken over Yahoo without a shot fired!)

Yang maintained a low-key tone throughout the presentation, as is his way (I kept imagining the performance being done by Microsoft’s Steve Ballmer, who would have sold it all hard until he popped a vein).

Nonetheless, Yang did get the message through that opening its platform up to third-party developers would be a big push in 2008 for Yahoo.

So, the widgets in the excellent mobile product, called Yahoo! Go 3.0, are laudable and much more innovative than anything out there, even though Yahoo has been too quiet about marketing its Yahoo! Go product until now.

But at CES, Yang brought Yahoo Connected Life Executive Vice President Marco Boerries (pictured here) out to show off the mobile apps, including one from MTV (Viacom head Philippe Dauman and MTV Networks head Judith McGrath were in the audience) that seemed fun.

More interesting was Yang’s presenting new concepts for its Yahoo Mail product, which will be more social, relevant and integrated. A lot of this functionality is already being used by the open-source email company Zimbra, which Yahoo recently acquired (and whose head Satish Dharmaraj I interviewed last week).

As I wrote in that piece, I love the innovations, including ranking of those you email with most frequently and instant mapping from email, as well as a plethora of great features for email.

So, one vexing part of Yang’s presentation was that this concept needs to become a reality tomorrow. He brought out Co-Founder and interim CTO Filo to basically promise “soon,” but I say: Make it snappy!

I know, we’re pushy when it comes to Yahoo, but it’s because we care!

Well, care is not the right word exactly, but we are certain that a powerful and pioneering company like Yahoo can out-innovate these Web 2.0 newbies who get ridiculous funding to make goofy widgets and have the nerve to call it a business.

Thus, we took the chance and his prone position after the speech surrounded by well-wishers to go up and say hello in person to Yang, whom BoomTown has known for longer than either of us would care to say.

And, miracle of miracles, Yang said it had been far too long since we had gotten together and agreed to meet in 2008, a meeting for which we have been asking and egregiously posting about forever, to no avail.

How much does BoomTown love CES? Not so much.

But if it gets me lunch with Yang, I love it. So, Jerry, it’s officially 2008 and I am waiting by the phone for your call.

Here is my video of parts of Yang’s keynote:
