FIRST TO COMMENT YEA!!! AND HEY GUYS I FINALLY GOT MINECRAFT SO HELL YEAH!!!!!
Didn't catch the live show so I don't know if you got an answer in the chatroom; I recognised the song in the listener contribution bumper (1:01:00) as an original song created by mrweebl - http://www.youtube.com/watch?v=L4AEEoX3d3E
I'm gonna have to get minecraft just because of these podcasts.
