Since this has been discussed a bit in the DUmmy threads about Rush/Elton John, I thought I'd make a more lighthearted thread here.
If you could choose any musical group/artist to perform at your nuptials, who would you choose? Money is no object, just pick someone, or more than one. And would you "discriminate" against any far leftist? And if you're already married, just pretend that you're having a re-committment/second wedding.
I would imagine that several of my favorite bands (of the neo-hippie progressive jam band variety) would lean left. I wouldn't care, I'd have them at my wedding in a heartbeat.
