“30 Rock” is back — for one night only.

In celebration of the critically-acclaimed NBC comedy’s 20th anniversary, cast members and special guests will unite at Radio City Music Hall in New York on Oct 11. The show will benefit The Boys and Girls Club of Harlem and will feature appearances by Tina Fey, Alec Baldwin, Tracy Morgan, Jane Krakowski and Jack McBrayer. More cast members and surprise guests will also be in attendance.

“Listen up tens, a five is speaking! Please join us to celebrate the 20th anniversary of the show Tom Shales once said ‘needs a better premise and funnier dialogue… and most of all a more commanding performer in the starring role,'” Fey said in a statment.

Ticket presales will begin Aug. 26 at 10am ET, with general sales beginning Aug. 27 at 10am ET

“We’re honored to be named the charitable partner for this celebration,” said Shaba R. Keys, president & CEO of The Boys and Girls Club of Harlem. “All net proceeds go directly toward the after-school, academic, and career programs that help more than 2,000 Harlem young people each year chart a path to their own futures—and we’re grateful to be part of a night this special.”
