WLD I would be thinking of the end of the eighties/early nineties (makng me 40 ish) Radio 1 on a Saturday night would broadcast a live concert followed by 2 hours of Freeman's Rock Show and then an hour of Heavy Metal before reverting to it's usual fayre. Freemans show always had a twenty minute or so feature spot for a certin band or artist from the past and I remember bands like Colosseum and Atomic Rooster getting an airing. Essential stuff when confinded to a basic laboratory from 1800 to 0600!
