here is a site i visit most days. it has variousl torrents[legal] of shows that have been broadcast on british radio. there are many different catagories, comedy, factual, drama, etc. however the one i like the most are the music documentaries. they've had a number of queen documentaries in the past which have been mostly pretty good.
anyway, just thought someone else may like this type of thing too. http://www.radioarchive.cc/torrents.php
