Dancing Queen? Really?

In case you missed it - McCain claimed that Abba's Dancing Queen was his favorite all time song! He claimed that his time in the Hanoi Hilton cut him off from music - and explains his bad taste. But he was a POW years before that song came out! Anyway, I'll be voting for the guy who likes Kanye, U2, the Stones, and Bruce. Which one sounds more working class?
