The Berkeley Rep’s box office blockbuster tracing the history of The Temptations runs through Nov. 5.

You know their music. Famous for the smash hits “My Girl,” “Just My Imagination,” and “Papa Was a Rolling Stone,” The Temptations helped define the sound of modern soul and R&B.

They were just five young men with big dreams and a special talent when they were discovered by producer and Motown founder Berry Gordy. The Temptations’ refined crooning and ostentatious costumes—signatures of the group through all its permutations over the years—made them a hit with both white and black audiences in the ’60s.

But their name proved prophetic. Even as their star continued to rise, the band members struggled with behind-the-scenes temptations that threatened to curtail their careers and tear the group apart.

Audiences are still fascinated by the real drama behind the songs and it shows: Ain’t Too Proud: The Life and Times of The Temptations, a new play telling the true story of the iconic band, made its world premiere at the Berkeley Rep in August—and has broken all the theater’s box office records in its first month by becoming the top-selling show in the Rep’s history, leading to it being extended three times. Ain’t Too Proud plays through Nov. 5.

Kennedy Prize-winning playwright Dominique Morisseau penned this new stage biography and Tony Award-winning director Des McAnuff helms the production. Through Nov. 5, 2 and 8 p.m. Saturdays; 2 and 7 p.m. Sundays; 8 p.m. Tuesdays, Thursdays, Fridays; 7 p.m. Wednesdays; $17-$62; Berkeley Repertory Theatre, 2025 Addison St., Berkeley, BerkeleyRep.org.
