Merman owns the number. No one else brings te same anger (and hurt) to the performance. The only part I don't think she does well is the stammer when Rose begins to break down.
2nd choice, for me is Peters. Her voice is not quite powerful enough but she makes you believe Rose as a person.
Lansbury I like a lot too but she does seem to strain her voice. Daly's voice was shot by the time she recorded it (she was better in the theatre - or maybe the visual image overrode the vocal deficiencies.)
Lisa Kirk sings it too much. Roz Russell tries to "act" it too much, and it does seem like a second rate post Broadway tour instead of the real thing. Midler is better but she is still Bette Midler and not Rose.
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
