Dear MMDers,  one of Matthew Caulfied's 1960s tunes may be "Popcorn"
(one word), written by Gershon Kingsley.  I have the sheet music,
bought in Berlin, and published by Sikorski, Hamburg, edtn. no. 93316.

The music also offers additional information : "Copyright 1969 and 1971
by Bourne Co., New York, N.Y. U.S.A."  I was hoping to tell you which
electronic group recorded it, but after lying unloved for 40 years in
a cupboard my 45 rpm disc has vanished.
