Margot Fonteyn, Fontaine and Michael Somes, Ballet performance of Les Sylphides C1950, 21F675

An interesting short film showing a young lady's admiration for Margot Fonteyn, and Michael Somes performing 'Les Sylphides' to music by Chopin...in about 1950 (possibly late 1940s) at the Globe Theatre London. Here we see some backstage activity, some stage performance, and a little narrative concerning how this looks through the eyes of a teenager of the time. I am a little unsure who to credit for this. It has GB Equipements as the releaser, and Castle Films as Distributor, with no other credits in the film. Some of what we do in life is not credited I guess.
