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):
