As the classic Gotham tuner marks its 70th anniversary this year, a revival of “On the Town” is set to open in October at Broadway’s renovated Lyric Theater.

John Rando (pictured), whose credits include “Urinetown,” will direct the musical, with choreography by Joshua Bergasse (“Smash”) in his Rialto debut. The show will be part of the reopening of the Lyric after renovations that will combine the sites of the original Lyric and Apollo theaters in the heart of Times Square.

Howard and Janet Kagan (“Pippin”) are shepherding the revival of the musical birthed by the high-wattage collaboration of Leonard Bernstein, Betty Comden, Adolph Green and Jerome Robbins.

The Kagans said they were happy to be part of the revitalization of the Lyric.

“This classic Broadway theater, right on 42nd Street in the heart of Times Square, is the perfect spot, and now is the perfect time to bring this big, brassy musical comedy back to the Great White Way,” the pair said in a statement.

The Kagans are promising that “On the Town” will feature the largest orchestra on Broadway, under the baton of musical director James Moore (“Follies”).

Other Main Stem vets on board for the production include Beowulf Boritt (scenic design), Jason Lyons (lighting), Jess Goldstein (costumes) and Kai Harada (sound design).

There’s no word yet on casting or an opening date.
