Do you think it's ridiculous for the Idol contestants to be singing Begees songs tonite?

I love the BeeGees and don't have a problem with theme nights. If you think it is just young kids, teens and the 20 something crowd that watches this show, then think again. Alot of the viewers for A.I. are over 40, yea, imagine that. I'm 55 and been watchin since season 1. I have friends and family from 40 to 60 who watch . They want to do songs the majority knows, my guess???
