Matthew Morrison, who plays glee club teacher Mr. Schuester on the FOX show, is currently performing "Up Close and Personal with Matthew Morrison" at 54 Below in New York City and at Sunday's performance, a source tells US Weekly that the actor dedicated a song to Monteith.

"Matt came out before the show started and said, 'We lost a great young man too soon. He said Cory was a beautiful person," then he told the crowd he would like to honor Cory with this performance and chose "What I Did For Love," a classic Broadway ballad from "A Chorus Line."

"He was very emotional on stage," the source continues. "It was difficult for him to get up to perform, but he did not want to disappoint anyone."

"Glee" co-star Lea Michele, who was also Monteith's girlfriend off-screen, performed "What I Did For Love" in the Season 2 premiere of "Glee."
