Vince Neil took his voice out for a test run, it didn't go well

I'm not sure what Vince was doing during quarantine but he wasn't successful at getting his voice in shape for the big Motley Crue, Def Leppard concert tour. He got on stage at a fair in Iowa and didn't even make it through the set before he blew his voice out. He left in the middle of 'Girls, Girls, Girls' leaving the band to sing backups to a phantom lead singer. I get it, age creeps up on you. Yet we see other singers in their 70's still able to work it onstage. Maybe it's time to get serious about some vocal work. The tour starts soon.
