Ex-Slipknot percussionist Chris Fehn was booted from the band earlier this year due to an ongoing lawsuit over finances with the rest of the band. Ex-Motörhead guitarist Phil Campbell was working on a new solo album at the time and decided to recruit Fehn to guest on a new song called "These Old Boots". Obviously Fehn drummed on the song (not with kegs!), and the track also features Twisted Sister vocalist Dee Snider and Motley Crue guitarist Mick Mars.
Campbell's new album Old Lions Still Roar is out on October 25.
