Alice Cooper's Hollywood Vampires performed a version of Ace Of Spades to a surprised audience of pop and rap fans during the gala event in Los Angeles. But Ken Ehrlich - who was struggling to include an unusually large number of artists' deaths in the weeks beforehand - hadn't planned anything special.

Ehlrich tells Billboard: "I will confess I didn't have a lot of Motorhead on my iPad. The metalheads have Dave Grohl to thank for that, because when I asked Dave if he would introduce that segment, he said, 'I'll do it - if you do something for Lemmy.'"
