It's April Fool's Day, dontcha know?

But all pranks aside, I don't think there's any chance of this happening.

Ehm, no. Joe's voice has improved a lot in the last years, I don't know how he's doing that! But I don't think that he has a better voice than Jon, or that he could put him in shame.

Nickelback and Daughtry already opened for Bon Jovi. I wouldn't be surprised if another mediocre band opened for Bon Jovi.

Or another mediocre solo act as David Bowie.

Say what ya want but Def Lep opening for Jovi would be awesome!

I don't know. Jovi is my favorite band, but at times, it's painful to listen to Jon sing some of the songs. Joe has no problems whatsoever, even on songs like Photograph.

As for the band themselves, no contest - Leppard would eat Bon Jovi alive on stage. And that's odd considering Bon Jovi has (or had) a better guitar player and drummer (though even with one arm, that's debatable). Def Leppard sound absolutely awesome live.

Just looking at the bands performing their latest singles, it's not even close:

To take it a step further, listen to how both bands sound recently playing their biggest hits:

Bon Jovi:

Def Leppard:

Def Leppard still really rocks and Joe can still hit the high notes. Jon doesn't even attempt to sing them.

Yeah, because either of them are in the same league as Def Leppard.

Joe has worst voice is rock IMO of course

It wouldnt
Def leppard suck balls
