Zac Efron reunites with 'High School Musical' castmates Corbin Bleu, Lucas Grabeel

NEW YORK, Oct. 7 (UPI) -- Zac Efron and Lucas Grabeel from High School Musical got together on Tuesday to take in a Broadway Show starring their other HSM castmate, Corbin Bleu.

Efron posted a selfie of the three of them post-show with the caption, "@mrgrabeel and I saw @corbinbleu DANCE on AIR ala Fred Astaire last night. He tapped "Firecracker" and lit the stage on (fire) with his moves! Check out #HolidayInnMusical #amazingshow #theboysareback."

Bleu stars at Ted in Holiday Inn, The New Irving Berlin Musical which is loosely based on the 1942 film starring Fred Astaire and Bing Crosby.

Grabeel also posted a post-show selfie, this one from the stage.

"Just a couple of wildcats on a #Broadway stage. @corbinbleu killed it last night in #HollidayInnMusical! @ZacEfron So much love for these guys," the caption said.

Holiday Inn runs through January.
