Delia's papers contain two sheets of manuscript for a piece called S.F.; at the foot of the first page she writes:
Michael Duhewell[?] version: add vibrating voice ...
which suggests that she produced two versions of the same piece, and on the back of the second page `re her "S&H + a better bass line" and "Munich". The original Science and Health was composed on 15th July 64 and Munich was started in June 1965.
She also mentions "SF" among the tracks she was thinking of reusing for the ICI Fashion Show held on 6th April 1967.
What does "S.F." stand for? Not Shadow of the Pharoah, which is from 1972.
