No, there's nothing wrong with asking, and Gracie herself talks about it really often. Remember she never really cared about the scandals she made and she loves talking about her wild times, whe was interviewed by VH1 to talk about this very incident and she has the same attitude as always. I found the footage and shared it with everyone in this blog, just look around the blog, or look at my posts and you'll find it. It's the whole live performance and it has a respectable sound quality. It isn't as messy as you think, all songs are preformed entirely (though some sources say she REFUSED to sing the songs the way she was suposed to), some are crappy, like Somebody To Love, and she only makes some remarks about the war on Wooden Ships when she sings her line "Can you tell me please, who won?" she starts asking "WHO WON THE WARRR?" but nothing too bad. In the end the audience even asks for an encore. Unfortunately that's only the audio footage and there ain't no video footage available, though the VH1 documentary shows some parts of it. Bettery Lyin' Down is also fun to listen to, specially since Grace states she wishes she had a penis (something she talked about really often, like on a early version of "You Wear Your Dresses Too Short"live, where she asks the audience if they want to see HER cock and the audience lols).
I don't know why so many people on this blog think it's offensive or disrispectful to share this performance, I think they exagerate. I love the JA/JS live performances and I think if any fan is intrested in it, should be free to ask for it. I'll share it (and any other live performances) with whomever asks me to as I've done before.
Enjoy the concert!
