Michele, Monteith's girlfriend, and show creator Ryan Murphy gathered the show's cast and crew, and they shared memories and music in "an emotional celebration" of Monteith's life, according to Twentieth Century Fox Television.
"Glee" begins its fifth season on Sept. 26, a week later than originally scheduled. The show will air a tribute episode honoring Monteith that will address the death of his character, Finn, Murphy earlier revealed.
The 31-year-old actor had been on the show since it began in 2009, playing the quarterback of the football team who joins the glee club.
Monteith was found dead in a Vancouver, British Columbia, hotel room on July 13. His death was ruled an overdose of heroin and alcohol.
