ven though I admire Roger's player, this is unlikely. Studio players
then and now are truly amazing and can play just about anything, in my
experience.

As I said, I'm basing my comments on remarks made by the band members
during an interview. IIRC it was David Crosby making that particular
comment. This was post prison so there's a good chance he was sober
and I can't think of any reason for him to lie about it.

There's still the matter of learning the songs as well as being able to
play them. Might just have been simpler to have somebody who already
knew them and could play them as well as anybody they might hire. Who
knows, I just prefer my version.

Does make you wonder how many of the British bands plyaed on their own
albums.
