I'm listening to Desert Island Discs on Radio 4 at the moment (the repeat) and Kirsty Young is talking to the animator Oliver Postgate (Bagpuss, Noggin the nog, clangers). His seventh choice, just played, is the beautiful Introspection 2 by Thijs Van Leer. I've never heard a Van Leer track on the radio before. About time. Let's hear more. See here.
