Here are 12 albums of the Lads at the BBC. A bunch of unheard stuff here(not included on official release). From what I've heard so far, it's the original shows..so there are other artists performing too. You'll have to look around to find everything since there are time restrictions on the downloads, but others have re-upped them to other sources. Pretty decent quality too.
