Page and B.B.?

[Kevin Wilson <kmwilson@xxxxxxxxxxxxx>]

I am reading a book on Eric Clapton (Crossroads-Michael Shumacher) and
there is a photo included showing Clapton, B.B. King, and a third
guitarist involved in a conversation.  It is a photo taken by Michael
Ochs and it was taken during one of King's performances at New York's
Cafe Au Go Go.  The third guitarist is in the right corner of the
picture and the photographer was positioned so that he was almost
looking over his shoulder.  The small bit of the face that I can see,
the design on the sleeve, and the guitar he is holding (appears to be
a Gibson because of the headstock and tuning pegs, as well as the
cutout around the  fret hand) lead me to believe that it is Page. 
The hairdo on Clapton, a Hendrix-style perm, leads me to believe that
the photo was taken during latter-day Cream.  Why is this of interest
to me?  Because I have never heard of any performance which teamed
B.B., E.C. and Pagey.  Has anyone else heard of this?  It would
certainly be an interesting show.  Thanks.
