Lea Michele revealed at Friday night’s Glee Farewell Panel at PaleyFest that she will be singing the final song of the series.

It is a tune written by Lea Michele’s Glee co-star Darren Criss called “This Time”.

Lea Michele said that no other song that might have been chosen for her final goodbye “could have encapsulated the whole experience.”

Lea Michele added, “That was the day I feel to my knees and cried. I got to say everything to everyone that I always (intended) to say but you can’t think of the words. And he wrote them.”

Criss said of his song, “My main thing was to write a song for Lea. It’s not just my own vanity.”

Glee!

He added that the song is “a love note for the entire series.”

Lea Michele’s highly anticipated final song is just the last link in the long chain of Lea’s goodbye process.

As the show wrapped filming for the last season and the finale last month, Lea Michele took to social media to share her joy and heartbreak as Glee came to an end.
