Yes, mike, there is a script available from some theatrical publisher people...not sure how you get a copy. You cant alway buy a play script in a bookshop,some you kind of get an actual typed script. One kwy elemnt of the show was the actuality recordings( interviews with people in the street), and those recording also exist because I heard them all the other day. Whether it would be worth reviving I dont know. Probably a bit like performimg the Monty Python Scripts or "That was the week that was" shows with new casts..probably not a good idea!
But we did have a reunion party the ther day and sang a lot of the show, intercut with actuality, and it did start to devlop a head of theatrical steam.
