I have two different copies of the "William Tell Overture."  My better
copy is on a QRS Recordo roll, number M-64510.  This is an expression
roll.   The other copy is on an  Artempo Roll, but I do not have access
to this roll, so I do not recall the number on this roll.  If I can
locate the roll I would gladly give it to you.

Good luck, and stay safe.
