Simon And Garfunkel - mrs robinson, 1968

"Paul had been working on what is now 'Mrs. Robinson', but there was no name in it and we'd just fill in with any three-syllable name. And because of the character in the picture we just began using the name 'Mrs. Robinson' to fit […] and one day we were sitting around with Mike talking about ideas for another song. And I said 'What about Mrs. Robinson.' Mike shot to his feet. 'You have a song called "Mrs. Robinson" and you haven't even shown it to me?' So we explained the working title and sang it for him. And then Mike froze it for the picture as 'Mrs. Robinson'."
