OK, I have an admission to make. Although the linked "movie" version above is a rerecording, I actually played on the original release of this awful novelty song. So I might be the reason the bass part (mostly under the CB radio chatter) has some active moments.

Drummer Bill Berg and I occasionally travelled from Minneapolis to Omaha and St. Louis in the mid-70's to work for a jingle company and this was one of the sessions we played on. Usually 3-songs in 3-hours so we probably made about $30 each on it and figured we'd never have to hear it again. But no. Pop music can be fickle! Eventually they sent me a framed Platinum Single (!!) but I couldn't decide if I was happy or just embarrassed.
Don't tell anybody ok?
