Piano on "Oh Well Part II"

[BklynBlue]

Been listening to "Oh Well Part II" - really fascinating piece - and it struck me as ironic that while most writers site Hendrix's influence on "Underway" (I have to say I can not hear it - either in it's original form as released on "Then Play On", or the full length version from "The Vaudeville Years") I do sense some of the feel of "Little Wing" in the second melody line, which the piano picks up about six minutes into the combined nine minute version -
Which actually brings me, in an admittedly circuitous manner to my question - does anyone remember having read anything as to who is playing the piano?
There is not much to be heard - probably no more than a minute all told, and in two separate sections at that - in the middle, and then again at the very end.
The notes to the CD edition say it was Christine Perfect, and the playing certainly flows more than what I associate with Spencer's style, but I was just wondering if anyone had secondary source of verification.
From experience, I have a lot more confidence in the knowledge of the Ledge members than I do in those who write the liner notes.
