I'm sure Rush didn't suggest Elton John, but you have to choose what's worth fighting over.
What's a Million Bucks to Rush? Obama got McCartney for free, and he even got some Bush Bashing as a bonus.
If I were Rush, I would have paid a good conservative entertainer to play at my wedding. It seems a bit hypocritical to pay a left-wing socialist to play at his wedding. He could have picked better entertainment for sure. Very telling.
