My wife wants to go and see one of the forthcoming musicals in Zurich, most likely Grease or Rocky Horror.

Does anyone know whether these are likely to be completely in English or not? I'm assuming the songs will be but not sure about the rest!

Thanks in advance!

I saw Hair several years ago and it was all in English.

I think it was a US cast though.

I don't know if with a Swiss cast that you could assume the same.
