Bands you've seen play live with different lead singers

This topic is inspired by New Creation's topic about artists you've seen with different bands.

Bands I've seen with different singers:

Killswitch Engage with Jesse in their early days then Howard a few years later. I preferred KSE with Howard.

Iced Earth with Matt Barlow and then with Tim Ripper Owens a few years later. I preferred Ripper

Living Sacrifice with DJ and then multiple times with Bruce. I preferred DJ, but only got to see them play 2-3 songs from Nonexistent before Jason Truby blew up his amp and stopped the show early for Mortification to come on.

Great topic! I had to think about it and no, I don't think I've ever seen a band with a different vocalist.

I had tickets to go see Ian Gillan sing for Black Sabbath (way back in the day), but they cancelled the show.

Saw Steven Patrick and Eric Wayne in Holy Soldier

Saw DLR, Sammy, & Gary Cherone in Van Halen

Petra Journey and Van Halen

I'm probably forgetting a couple, but here are ones that I remember...

Queensryche - Tate and La Torre
Exodus - Souza and Dukes
Petra - Volz and Schlitt
Tourniquet - Ritter and Easter
Holy Soldier - Patrick and Wayne
Living Sacrifice - DJ and Fitzhugh
Newsboys - Furler and Tait
