Jack Tarling recorded COME INSIDE, YOU SILLY BUGGER, COME INSIDE on a cassette called "Down in the Fields Where the Buttercups Do Grow: Jack Tarling Sings Songs of the Essex/Suffolk/Cambs Border," Neil Lanham Tapes NL01, 1996.

This review says the song is better known as THE LUNATIC ASYLUM.

Chas & Dave recorded a song called THE LUNATIC ASYLUM on their album "Don't Give a Monkeys," EMI LP #3303, 1979, but I don't know if it's the same song.
