Who knew you had to rehearse final bows?

But for director/producer Ezra Flam, nothing can be left to chance, especially when you have more than 70 students on the stage in the last scene of Belmont High School Performing Arts Company’s production of Cole Porter’s musical “Anything Goes” that opens Thursday, March 26. 

Playing a theater’s version of a traffic cop on stage during Tuesday’s dress rehearsal. Flam is calling out directions to a slew of students who first came together in try outs before Christmas to claim a spot in the annual spring musical. 

Just minutes before, Flam’s choreographer Jenny Lifson demonstrates to Reno’s Angels – the 10 featured female dancers – just how to hold up the hands and for the sailors to remember to “smile” while performing a series of tap steps before lifting their “Angels” in the finale. 

“Not one of them knew how to tap,” said Lifson, pointing to the boys’ in uniform on the stage.

“Look at them now. That’s impressive,” she said.

And while there were some hiccups during Tuesday’s run through – someone forgot to grab a chair at a scene change and the spot light went hunting for a feature actor during a scene – the majority of the afternoon rehearsal showed a polish few other high school groups could match.

Performances are Thursday, March 26 and Friday, March 27 at 7 p.m. and two shows on Saturday March 28; a matinee at 1:30 p.m. and the final show at 7 p.m.

Tickets are adults: $15 in advance, $18 at the door. Students: $10, Chenery 8th Grade Students: $5.
