Hmm. You probably did. As I say, I certainly remember many giving it a damn good pelting. I think it was first broadcast here in 1972. Whether the signature tune was an original or lifted from something else, or when indeed it or whatever it may or may not have been nicked from was recorded, I don't know. Let's find out, shall we? I should have done this earlier, really.
Hmm. From
http://home.hiwaay.net/~emilyj/index.html, we find the following:
'AYBS?'s unique theme song, which featured a lift girl (voice of Stephanie Gathercole, Mr. Rumbold's first secretary) announcing each floor over a 'cash-register' rhythm track à la Pink Floyd's 'Money', was written by series co-creator David Croft, who was trying to eliminate the need for expensive union musicians when deciding on a signature tune. The sparse musical accompaniment was arranged by Ronnie Hazlehurst.'
And for those of a particularly obsessive nature, you can download the full version of the theme tune. Well, it makes a change from listening to Money again.
