Which artist/band do the New Directions pay homage to in the first two episodes of the season?

Who steals Finn's letterman jacket (from Kurt) while McKinley and the New Directions spend the week grieving his unexpected death in "The Quarterback"?

A tribute episode to the late Cory Monteith/Finn, the cast couldn't get through a single take without breaking down (understandably so)

I Still Haven't Found What I'm Looking For

Season 1: Mr. Cellophane; Season 2: Nowadays/Hot Honey Rag; Season 3: Cell Block Tango; Season 4: All That Jazz; Season 6: Mr. Cellophane (reprise)

How well do you know season 5 of the hit show, Glee?
