For me it it's the Mister Men with Arthur Lowe telling the stories. We had most of the books at home (as well as the John Mouse and Roundy and Squary books) so that helped. I liked the music in Mr Benn but I always ended up watching either the cowboy or the hot-air balloon - never the knight! Bagpuss, on reflection, was rather quaint but had a sweet side. I couldn't stand Madeleine, the bossy smartarse rag doll.
Never cared for The Flumps or Pigeon Street.
