Yup, this thread caught my eye! I checked with the resident expert to get the facts. My husband Frank was bass player and vocalist in the band "Clean Living" which recorded this song on the Vanguard label in 1971. It was on the self-named album as well as a single, and apparently was pretty popular.

He says it was written by two guys named Ralph Segal and Ernst Neubach.

The Clean Livers claim that they used to goof off with this song to loosen up before a gig. At this, their first recording session, the producer gave them buckets of cheap wine and told them to loosen up with a few tunes. They cranked out this one, with the engineers, producers, hangers-on, everyone singing and yelling and having a grand old time. Didn't know it was being recorded, and never expected it to be a hit! So then this serious, folk/rock band had to live down this song that has forevermore followed them.
