I remember from my yoof, a Bonzos song that I haven't been able to find again. From what I remember, it consists of an apparently endless series of cliche classical music endings - each apparent ending, instead of actually ending, just goes into another deceptive non-ending. And it goes on and on like that until (ironically) it fades out.
Anyone remember the song I mean??
(There is another song, by Dudley Moore, that is based on a similar idea - but I'm pretty sure that's distinct from the one I'm thinking of.)
