After I saw that Peter declined to be interviewed, I wasn't interested in it.

Really, Peter!!! Do he really hate your old band or have bad blood? He really is a diva. It just makes me think of when he didn't do the RnR HoF because things didn't go his way.

I don't know what the story is with him not wanted anything to do with Chicago(it was probably said in the documentary, but of course I didn't watch).
