If you're a 'Glee' fan, next Thursday will be the saddest hour of television you'll watch. That's when the cast will remember Cory Monteith/Finn Hudson, who died from a heroin overdose, in 'The Quarterback' tribute.

Creator Ryan Murphy tells the Hollywood Reporter, 'Almost everything in that episode is from the first take of every performance because the actors and the crew had a really hard time shooting it. I've never seen a crew that you can't continue shooting because they've left the room sobbing. It was very hard. I struggled even working on it because what you're seeing is what they felt not just about Finn but Cory.'

The 'Farewell to Finn' episode begins with the news of Finn's death. Lea Michelle (Rachel), Cory's girlfriend on the show and in real life, won't appear until the end of the show. In addition to the regulars on the show, Amber Riley (Mercedes), Harry Shum Jr. (Mike), Mark Salling (Puck) Jayma Mays (Emma),and Dot Marie Jones (Coach Beiste) return to remember and mourn Monteith/Finn's death and celebrate his life.

Mjsbigblog.com has the list of songs that will be performed on the tribute:

Rachel will sing 'To Make You Feel My Love'
'Fire and Rain' by James Taylor
'Seasons of Love' from Rent '
Santana will sing 'If I Die Young' by The Band Perry '
Mercedes sings 'I’ll Stand By You' by The Pretenders'
'Never Surrender' by Bruce Springsteen

I don't know about you, but I'm going to have to watch this by myself, with a big box of Kleenex.  I will be bawling my eyes out.  I already had tears in my eyes just from watching the :30 promo video.

Glee will go on hiatus after the tribute, for the baseball playoffs and to retool the show, now that Finn/Cory is gone.
