Hi Glenn,  Billings Rollography Volume 2 lists your 'Toccata' roll as
follows:

  Toccata [Camille Saint-Saens]  611580
  Played by Harold Triggs, date 6/25.

Hope this helps.  By the way, the uncredited pianistes on your 'Duo'
roll of 'Three O'Clock In The Morning' are Edith and Laurel Pardey.
It uses exactly the same master which was later re-released as
Mastertouch D.194.

Cheers,
Robert Perry
