60s/70s? Corny and slightly creepy? That would have to be "Time of the Season" by the Zombies. Gives me the heeby-jeebies every time I hear it, but it's so creepy I have to listen and laugh at it. For example, I actually saw a televised live performance of the song on PBS the other night while channel surfing. I think it was a fairly recent performance by the reunited Zombies. They're well into middle age now. And they were standing up there, singing, "What's your name? (What's your name?) Who's your daddy? (Who's your daddy?) Is he rich like meee? Has he taken... any time... to show you what you need to live? etc. etc."
Creepsville. Yikes.
