A very interesting list of sheets. But there WAS an entire piano solo book for CLEOPATRA that included both the Caesar And Cleopatra theme and the Anthony And Cleopatra theme, plus a few more - all piano solos and the cover had the same art-work, and also from Robbins Publishing. I have a copy, except that my copy no longer has the cover art.
Many of the other North sheets you list, I just had no idea they existed. Thanks for your list.
