Understudy Margaret-Ellen Jeffreys is having a real “42^nd Street” moment – she’ll finish out the run of “Musical of Musicals (The Musical!)” at Playhouse in the Park, after stepping in when the original star suffered serious enough vocal strain to pull her off stage for the duration. (“It wasn’t “Phantom,” it was the Jerry Herman,” a not-to-be-named Playhouse fan observed at a holiday party last weekend.)

Jeffreys is roundly applauded as “fantastic!” by people who’ve seen her performance.

Now let’s just hope the cast stays healthy, because it was just luck that the ingenue role had an understudy. “Musical” is now playing without a net. Keep that vitamin C on hand!
