Well, going way back, FLAHOOLEY!
It's got some great songs, marked the Broadway debut of Barbara Cook, featured Amy Camus (who preferred top spell her name backwards as Yma Sumac..why, I'll never know!) who has a thrilling and unusual voice.... and it closed after just 40 performances and has never been revived. A wonderful cast album (and its out on DRG - give it a listen. It's early high fidelity mono but not sounding like antique 78 RPM records.)
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
