How Joan Littlewood changed Sheila Hancock's life

My interest in Joan Littlewood's Theatre Workshop at Stratford East and obsession with the original London production of Sweeney Todd meet in this video.

And it's all true. Here's R.B. Marriott reviewing the first West End performance of Make Me An Offer for The Stage (24 December 1959): 

Sheila Hancock, who originally made a personal hit in the production, repeats her success, and on the first night stopped the show with her singing of "It's Sort of Romantic". 

Miss Hancock is now unlikely to be in need of work in the theatre, but I hope that her originality, talent and personality will eventually be given far wider scope, not only in "suitable" supporting parts but in leading ones, for which undoubtedly she is equipped.
