Bagpuss was one of the truly great cultural experiences of all time - a devastating tragedy for those who are not old enough to have lived through it (Sorry Indie (et al.)!) :-)
I have 'The Complete Bagpuss' video - all 13 episodes. How's that for a confession?
The characters were Professor Yaffle, Madeleine the rag doll, Gabriel the toad and my favourites the Marvellous Mechanical Mouse Organ. Remember this:
Bagpuss, dear Bagpuss,
Old fat furry cat-puss,
Wake up, and look at this thing that I bring,
Wake up, be bright, be golden and light.
Bagpuss, oh hear what I sing.
