Bleu stopped by the PEOPLE Now studios on Monday, where he dished on his mini High School Musical reunion with Efron at his Holiday Inn Musical Broadway show.
“It was so good to have him come,” he said.
And it turns out, Efron was so impressed with his former costar’s performance that he gave him a standing ovation — in the middle of the play.
“When [the musical number] firecrackers ended he stood up,” said Bleu. “People usually throughout the show won’t have an ovation, but he stood up. It was just him!”
Bleu said he was touched when he looked out into the crowd and saw Efron.
“I could see him and I was just like ‘awesome dude.’ ”
Along with Efron, fellow High School Musical castmate Lucas Grabeel also attended the show.
“@mrgrabeel and I saw @corbinbleu DANCE on AIR ala Fred Astaire last night. He tapped “Firecracker” and lit the stage on with his moves! Check out #HolidayInnMusical #amazingshow#theboysareback,” Efron captioned a photo of the trio.
In the play, Bleu takes on the role originated by Fred Astaire in the 1942 movie. And while the actor literally danced his way across a basketball court in High School Musical, he said it was nothing compared his musical numbers in Holiday Inn.
Bleu said that one of his more difficult numbers includes both dancing and fire called “Let’s Say It with Firecrackers.”
“It’s all timed out onto the stage so as I’m dancing I have to move into certain spots,” he said. “And I take my hands in my pockets and I throw down and the [firecrackers] explode.”
