Revivals that topped the original productions? Well CABARET (199

for sure (although I DO miss "Meeskite.")
The 1971 NO NO NANETTE was sparkling and ran nearly 3 times as long as the original.
But my choicve would be Merman in the Lincoln Centre revival of ANNIE GET YOUR GUN (1966) about which she said "We only intended to do that for 5 weeks, but it was such a good production we took it on the road, then brought it back to New York to the Broadway theatre."
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
