Those SOny West End recordings were released for all of 2 seconds--very frustrating. I ended up with some like the "london" Company but others I just never saw a copy of Eric - The reason there is that Sony Canada only released the first batch (ANNE OF GREEN GABLES, COMPANY, BAR MITZVAH BOY and CABARET) here. Sony U.S. did not release these at all. Footlight and a few other specialty stores brought them in as imports.
THe 2nd batch had some more interesting titles: SALAD DAYS, PASSION FLOWER HOTEL, BEGGARS' OPERA, CHARLIE GIRL, FIDDLER ON THE ROOF, NO NO NANETTE and SWEET CHARITY but I was only able to track down a few of these thru E-bay. (The London FIDDLER ON THE ROOF has been released here in the Columbia Broadway series.)
One other London cast that was supposed to be included was ON THE TOWN but after it had been pressed and shipped they had to recall it: Instead of using the London cast tape, they had used the Bernstein studio recording with Walker, Comden and Green. They were going to re-release it with the correct recording but the series was dropped before that happened.
Cast albums are NOT "soundtracks."
Live theatre does not use a "soundtrack." If it did, it wouldn't be live theatre!
I host a weekly one-hour radio program featuring cast album selections as well as songs by cabaret, jazz and theatre artists. The program, FRONT ROW CENTRE is heard Sundays 9 to 10 am and also Saturdays from 8 to 9 am (eastern times) on www.proudfm.com
