Winterland 4/15/70 additional personnel

[Jim Powell]

The additional keyboards might be Freiberg, it couldn't be Hopkins.  I guess
the additional guitarist could be Duncan -- it doesn't sound at all like
Jorma or Cippolina or Santana, although the jam itself sounds rather like a
Santana jam.  It's hard to say much about the additional guitarist because
he's just playing a _real_ fast rhythm part.
