For those with a Gold account on Xbox Live, if you download the free Guitar Hero: Metallica demo you get four songs to play, including the master recording of Queen's Stone Cold Crazy. The other songs are Sad But True and Seek & Destroy by Metallica and No Excuses by Alice In Chains. You can play all four roles (guitar, bass, drums, vocals).
Nice for people like me who were just interested in this because of the Queen song. I just played some bass and pulled off some Deacy dancemoves, its pretty cool :D
