The production didn't mess with it in any way - much to our relief - so we were treated to Jerome Robbins original stylish choreography, Leonard Bernstein's glorious (if a little over zealously played) music and Stephen Sondheim's spot on lyrics. We loved it.
My only quibble was perhaps that 56 years on from its Broadway premiere some of the language in West Side Story now seems very dated "man" "you dig" and the shock value of the action isn't there quite so much. Perhaps a production with a contemporary twist could be welcomed - it hasn't done source material Romeo and Juliette any harm.
The performances were all excellent though. The America cast that has been touring with this production can sing, act and boy can they dance. Stand out for me was Penelope Armstead-Williams as Anita - a role that we can all fall in love with. She is Puerto Rican, proud but in love with America.
If you get a chance - go see.
