Def Leppard guitarist Phil Collen says he's “confident” the band’s summer stadium tourwith Motley Crue,Poison and Joan Jett will happen. On the Jeremy White Podcast, he said it will happen if “they get the vaccine rolled out… We really don't know. It really comes down to how everyone deals with approaching this pandemic and stuff." The tour, originally scheduled for last summer, will start on June 19th in Nashville.
