I'm looking for a version of the Beadles About theme. NOT the well known one where the song is sung, but the one they used later on in the show's life, without any vocals, just an instrumental. I think it was probably used on the last couple of series.
The only one I remember that was instrumental was called "Muvver's Ruin" and it's a KPM track from 15 or 20 years ago, from a an editor's companion style LP.
Whether it ever made it to CD or MP3, I don't know.
