Rob Halford Rocks Alice Cooper’s ‘Christmas Pudding’ Show

Alice Cooper's annual Christmas Pudding show took place on Dec. 17 and the shock rocker was surrounded by plenty of special guests upping the event's metal quotient. Judas Priest singer Rob Halford, former Korn guitarist Brian "Head" Welch and former Motley Crue singer John Corabi (who can perhaps apply for his former job if his predecessor and replacement Vince Neil actually does bolt) were all on tap at the 11th annual show at the Comerica Theater in Phoenix, Ariz.

Halford looked every inch the Metal God that he is, performing in all black and lots of leather. No Santa-style red suit for him. His renditions of 'Breaking the Law' and 'You've Got Another Thing Comin'' were festive, in the metal way, of course.

When Halford joined Cooper, Head and others for a rendition of 'Run Rudolph Run,' there was fake snow falling, landing on Cooper's inky black hair. Snow in Phoenix? Only at a rock show, folks. There was also a Santa Claus on stage, too.

Notice that when Halford and Cooper are singing 'Run Rudolph Run,' they are doing so off a teleprompter. They barely make eye contact and are looking down. It's not a metal song, so it's not like we can fault them for doing so.
