Earlier this evening, I was watching "The One Show" on BBC1. One of the guests being interviewed was comedian Lee Mack. His grandfather? was also a stage comic, and the show had found a playbill for one of his performances. It mentioned this song.
For curiousity, I googled the title. First result at top of search list (and only one obviously mentioning the song) - This Thread.
Typical!
Quack!
