Sondheim was indeed screwed...22 years ago when he lost the Best Score award (for SUNDAY) to Jerry Herman (LA CAGE.) He survived that slight.
He has survived critics misunderstanding and mis-representing his work.
He has survived winning Best Musical for PASSION only to have the show close after an 8 month run, while the show it beat (BEAUTY AND THE BEAST) is
still running.
He has survived audience indifference, watching as they flock to see the latest ALW garbage multiple times while some of his best shows struggle to stay open.
He has survived umpteen revisions and workshops of WISE GUYS/BOUNCE, which has still not managed to get to Broadway.
And he has survived Tony losses before. (I am reminded of an interview I did with Charles Strouse many years ago when he commented that "winning a Tony award is always nice, and losing is not, but in the end it is the shows that matter.")
The past 5 seasons have had one Sondheim revival nominated each year, and two (ASSASSINS and INTO THE WOODS) won the award. The best way to honour Sondheim is to keep his shows coming back in new interpretations to intrigue, entertain and challenge audiences while at the same time winning over new fans.
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
