the excel one is mediocre, but bearable - some good points, and Cliff's notes is slightly better - Cliff's Complete is also alright. Notes on the web seem to be the go
Just look up Peter Brooks on the net - his 1971 production, there is heaps of info on it, even if you don't get to see it - I haven't, but I've written about it.....
:confused: that's all I can tell u i think....
good luck
