'I'm the Urban Spaceman', a hit for the Bonzo Dog Doo Dah Band, was produced by which one of the Beatles using the alias Apollo C. Vermouth?

"I'm the Urban Spaceman" was the Bonzo Dog Doo-Dah Band's most successful single, released in 1968. It reached #5 in the UK charts. The song was written by Neil Innes and produced by Paul McCartney and Gus Dudgeon under the pseudonym "Apollo C. Vermouth". The B-side was written by Vivian Stanshall. Innes won an Ivor Novello Award in 1968 for writing "I'm the Urban Spaceman".

A well-known staging of the song involves Innes performing solo while a female tap dancer performs an enthusiastic but apparently under-rehearsed routine around him. This skit originally appeared in a 1975 edition of 'Rutland Weekend Television', with Lyn Ashley as the dancer, and was more famously revived in the 1982 film 'Monty Python Live at the Hollywood Bowl' with Carol Cleveland taking over the role.
