View source for S.F.

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 are her "[[Science and Health|S&H]] + a better bass line" and "[[Munich]]", which are from July 64 and Summer 1965 respectively. 

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.
* Not [[Survival of the Fittest]], which is from 1968.
* Maybe [[Tonic Sol-fa]], broadcast in November 1966?
