CARL RUSSO PHOTOS: Play Among the Stars Theatre Groupe embraces imperfection. Along the way, the Salem troupe of adults with disabilities celebrates music, dance, costumes and the unexpected.

Founder Sara Brown presented the first show in 2000, and in so doing set a constellation of unlikely performers in motion.

The troupe’s newest production, the musical “At the Hop,” is set for Saturday, April 28, on the Seifert Performing Arts Center stage at Salem High School.
