Did you ever hear Slash's self-titled solo album from 2010? He worked with a bunch of different singer's for the album.
He did one track called "Crazy" with Chester Bennington of Linkin Park but the band blocked it from being released. So Slash re-recorded it with Lemmy from Motorhead, changing the lyrics to "Doctor Alibi".
Well, time has passed and Chester is no longer with us. After getting the ok from Chester's family, a clip of the song has leaked on a podcast... and that means it's made it's way to the Internet!
I hope at some point, we'll get to hear the whole thing. Enjoy this little snippet.
