NANETTE is dated, but as rewritten in 1971 it is done as a send-up of 1920s musicals (similar to THE BOY FRIEND, except NANETTE is authentic.) The score bubbles like champagne, and the book..well it fills time between the songs. For a show that was such an unexpected hit in 1971, the revised version has been little seen since.
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
