This is in response to Neil Smith's request for a Wurlitzer 150 roll
or MIDI file for "The Thunderer".  According to Matthew Caulfield's 150
roll catalog, this march can be found on two 150 rolls.  One roll is
titled "Louis May's Special #101".  It is tune #3 on the roll.  The
other roll is titled "#1. (Courtesy of Louis May and David Stumpf)".
This roll has six marches; "The Thunderer" is the second march on the
roll.

I haven't seen either of these two rolls for sale.  Maybe someone
reading this posting will know whether these rolls are still available.
