Well it was either at Treblinka or Sobibor they had an orchestra. It was a very popular one that toured Europe. Since they were Jewish they were put in the camp to play music as the people were being led to their deaths. Think of them as the Lester Lanin of Europe. So I guess you could do a musical about that.
“Playing For Time”, a made-for-TV movie, starring Vanessa Redgrave, makes me cry whenever I watch it.
I could not, however, see it as a musical.
