I've wanted to download this music for awhile, but wanted some input on which to purchase. There are 4 different versions on iTunes: London 1983, London 1995, London 1993, and the International album with Petula Clark and David and Shaun Cassidy. Which recording best represents the show? I really hope they do a revival on Broadway or I can see it locally because this music is gorgeous! Thanks in advance for the input.
