Alembic Rehearsals 12/68?

[Jim Powell]

I don't believe that the Alembic Rehearsal tape Ihor just posted a list for,
dated "12/68" is actually from nearly that late.  I don't believe the
keyboards on the tape is Constanten and the way they're working on this
material seems too early to be Dec. '68.  I would guess that this tape comes
from more like Dec. 67, or from a date much closer to Dec. 67 than to Dec.
68.
