Charming programme! Have you got any more of them, please?
Sir Patrick Moore was good on the xylophone.
Funnily enough, around this time I took part in a BBC tv show called "What's That Noise?" headed by the great Craig Charles. Another music programme for young people - and with (I think) rather more impressive guest contributors! (The brilliant Tristan apart, obviously).
I have been looking for this for years. Thank you, this brings back good memories.
