In the late 60's I was an apprentice electrician at Dartington hall in the Barn Theatre. I met Marcel Marceau helped set up the stage, lighting etc a nice guy and brilliant. Then in the Great Hall set up and met Ravi Shankar load of huge cushions for him to sit and play his Sitar. Probably met more as they had famous people playing Grand pianos, Harpsichords, Quartets and Opera people but I was young and not interested lol.
