Before we get started, I want to remind everyone that this is not a regular episode of Glee and you do not have the same freedoms you otherwise do. Any complaining about song distribution or what songs are being sung will be deleted IMMEDIATELY.
At this point we know that they will be singing Seasons of Love from Rent, possibly to open up the episode. We also know Amber has been in the studio for this episode.
If you have anything to add, feel free.
