Sorry, can't help with the TV, but BBC7 has broadcast reruns of a radio show called 'Does the Team Think?' on which Askey was a regular panel member.
Don't think it's scheduled at the moment but it'll probably come round again.
Many classic BBC radio shows are avalable as MP3's on file sharing networks, but downloading them is probably a very naughty thing to do scold and I certainly woudn't recommend you look for them like that. wink
