Livin on a prayer key change

I have a friend and he's a big BJ hater and he says that Jon never sang the "woah-oh livin on a prayer " part in the key change. I showed him the '86 concerts from Bradford,Dortmund and Stockholm where he clearly sings the high parts but he is still not convinced . Did he sing the high parts in other concerts from '86 or even early '87?

Apollo Theatre, Manchester.

At least according to your own post in another thread by you on pretty much the same subject.

If you're friend doesn't wanna be convinced by you showing him four occassions where Jon sang the key change, one more performance won't change anything either.
It's very possible that there were some other documented ones from that era, but I'm too tired to go through them since most of the SWW bootlegs are sounding quite bad, unfortunately.
