Bzzzt! I don't think either of the last two moves really qualifies. I mean, yes, they were on in the seventies, but by that token you might as well claim, say, The Bible as a 70s book.

Pending adjudication on that, I'll go for Ken Russell's Tommy.

[matt] I kind of see your point, but do you really mean we have to abandon things that were created in the 70's but are still around? And was the bible written in the 70's? I think we should be told.

I'm sure someone's translation was written in the 1970s. Anyhoo...toning it down with Billy Joel's Piano Man.

Blowping BJPM with Up Town Top Rankin' Ting!

Is Kraftwerk authentically 70's enough?
