If they saved the necessary six figures to record this, then Lord love 'em, but it seems rather pointless. The new orchestrations are about half 1/2 the size of those on the existing recording, and none of the vocal performances are improvements - why listen to Kropp when you can hear young Peters? And although Margherita was hilarious in her role, I'd have to say no one else in this production was more than serviceable.
Now, if they had recorded the 1987 Lamb's Theatre revival, I'd like to listen to that. That was a sextet of great performances, and it would be wonderful to have a recording of the original two piano and percussion charts.
