I think he gave it a shot at one of those Runaway Tour shows some time ago.
There also was a promo radio show for DA in 1997 where he tried it upon request, but failed for most of it. Can look it up and upload it later on.

Here you go :) House of Blues 1997-07-31 JBJ solo

Haha, oh boy. Gaga really should have studied the pre-chorus harmony a bit closer ;) She tried all sorts of combinations of notes without nailing it. She truly has a killer voice, but that didn't really work out as good as I hoped for.

This must be one of the first covers of the new album in TV:

BON JOVI - Brasil 1995 (These Days Tour Live)

I'm searching for a specific video on Youtube, but have no idea where to find it anymore. There was a behind the scenes video of the tour (either 2011 or 2013) where they interviewed the guy that was triggering the backing tracks from behind the stage and he explained his setup. Anybody remembers that?

Soundcheck from a 2013 show with Phil.

Bobby sings IBTFY. Some random screams by David and Phil included!

dont know if this has been posted already but I just found it on youtube and think it's hilarious :D
