The Reprise! Theater Group is an organization that stages musical revivals for short runs on shorter budgets. Four times per subscription season, they mount some semi-lavish production at Freud Hall at UCLA with minimal sets and even more minimal rehearsal time. But there's always a maximum of talent and it makes up for an awful lot.
About Stefanie Powers' performance in the revival of On Your Toes, the 1936 show by Richard Rodgers, Larry Hart and George Abbott:
Stefanie Powers played the rich lady who manages the ballet troupe and she seems to have aged about a week since she was The Girl From U.N.C.L.E. She had a nice star turn and handled her musical numbers quite well. (One joke was added to the script to reference her run as co-star of Hart to Hart).
