Skip Greiner was asking about the J. Lawrence Cook arrangement of
"Beer Barrel Polka".  In addition to the QRS rolls listed in the
Billings Rollography, the Aeolian Company also stocked the same roll
put out by Q.R.S.  My Aeolian catalogue lists this title played by
J. L. Cook with credit given to Q.R.S.

In other words, Aeolian sold this exact same roll (Q.R.S. 7009) but
under the Aeolian label.  After J. L. Cook left the Q.R.S. factory,
he worked at the Aeolian store on 57th Street in Manhattan.  That store
had in stock most of its own piano rolls.  But since that store has
been closed for over 40 years, I don't know of any other outlets that
would stock Aeolian rolls.  Maybe someone else would know.
