I'm a big fan and I've seen her live quite a few times, she sang Songbird once and at one of the
I'm Still Here, Dammit! shows I saw, she did a medley of various female rocker songs that included a few lines from Over My Head.
I must say, though, that she was at her finest when she told stories of her affair with Stevie amongst afghans and frilly pillows.
I have a few bootlegs from over the years, I'll check to see if there's any Chris or Stevie mentions on them.
