It is not so much a song as a comic monologue in which the speaker introduces the musicians who ostensibly appear on the recording.
[4] Stanshall first introduces the seven members of the Bonzo Dog Doo-Dah Band, who are credited with their actual instruments, over a vamp that resembles Duke Ellington’s "C Jam Blues".
Some of those named will now be unfamiliar to listeners outside mid-20th century Britain, such as Billy Butlin, Val Doonican, Max Jaffa and the comic strip character Lord Snooty from The Beano.
[5] The "sessions gorilla" portion of the recording originally ran "And now just arriving, Quintin Hogg on pig grunt".
An excerpt of the song, with an adapted commentary sounding like Stanshall (actually performed by Bob Monkhouse), was used in a 1988 television advertisement, made at Passion Pictures and animated by Chuck Gammage, for the Cadbury Creme Egg.
