Some shows recoup with post-Broadway income. SWEENEY TODD and INTO THE WOODS both moved into "profitable" status thanks to post-Broadway tours.
Hal Prince once explained that there are Hits and Flops which is purely a box-office term. And there are Successes and Failures in terms of what the show accomplishes. On the BROADWAY documentary he sums it up saying PACIFIC OVERTURES was success. "It was a flop, but it was a success."
Some people use a show's financial status to justify their like or dislike of a show. Unless you invested in a show, its financial status doesn't matter at all.
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
