I have a recording of The New Wine Singers "Live at the Hungry I" and the song is on it. My guess is that the recording is from the early 60s.

FUNCTION JUNCTION

Are you from Function,
From Function Junction,
Where those Function Junction suction pumps are made?
Are you from Function,
From Function Junction?
Well, I'm from Function too.

Don't cry lady,
I'll buy your goddamn violets.
Don't cry lady,
I'll buy your pencils, too.
Don't cry lady,
Take off those dark glasses.

Hello, Mother!
I knew it was you!
