After six seasons of singing and dancing and a shed load of emotional highs and lows, including the very real heartbreak of cast member Cory Monteith's death, the curtain finally falls on Glee tonight. The final two episodes will show a flashback to how they all met back in 2009, and a flash forward to 2020 to see what they have all done with their lives. We won't ruin it for you, but needless to say they wrap things up nicely, with familiar faces returning and a rather apt closing number of "I Lived" by OneRepublic.Yep, you may need the tissues at the ready for this one.
