FH hates Cannon in D which was my first choice.
My next choice was this song: http://www.youtube.com/watch?v=QgaTQ5-XfMM
But some people I've bounced the idea off of think that it sounds sad, which is obviously what I don't want. But it does get happier, I think, towards the end.
Once I found that I really liked the idea of doing a classical rendition of a modern song, but I can't think of any others. Anyone have suggestions?
