Gosh, I'm sorry to post a contentless comment, but watching this just made me so happy.
Which if you think about it, Don't Worry Be Happy would have to be the most ironic possible song to cause a person to storm off.
I guess the audience kept mum on the requests, because my friend says it was one of the best shows he's ever been to. And he's been to a lot.
Note: coming from me, this is just heresay. I can't actually testify to Bobby McFerrin's hatred of Don't Worry Be Happy.
He wrote it in an hour or so because of being frustrated. I can imagine if you have 'great plans' and all people recognize you for is a thing that you whipped out like that it could get a little frustrating.
The real compliment is in that his musical genius is such that he could even do that.
There are other examples of that, I think that such huge popularity of a thing you whipped out in a short time causes people to think of you as a 'one hit wonder', and I'm sure that is not what Bobby McFerrin is all about.
It's a bit non-traditional, but one of my favorite classical CD's is where he sings the violin solos for various pieces. Link to album "Paper Music" is here:
For all the tracks marked "Voice", he's using his voice as a solo instrument, but not singing words. The description sounds cheesy, but the result is surprisingly effective -- simple and haunting.
