It came in right at the end of the season without a lot of advance publicity. Even so, it is such a well loved title and Patti was still hot from EVITA so everyone expected it to run. An then it abruptly closed. Around the same time there was a short-lived revival of THE WIZ. These two plus the failure of the MAME revival a few months earlier and the 1-performance flop of a revival of TAKE ME ALONG the following season more or less put an temporary end to big musical revivals.
To add perspective EVERYTHING was failing. Broadway was not a tourist friendly area. Half the theaters were dark. THE RINK and BABY barely lasted 6 month each. There were not a lot of big box office hits, (LA CAGE was one of the few) and it did not turn around until LES MISERABLES arrived in 1987 followed by PHANTOM in 1988 and MISS SAIGON in 1991.
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
