VIDEO: GLEE Says Goodbye- Watch ALL the Performances from GLEE's Emotional Series Finale!

GLEE said a final farewell on Friaday at 8 pm on FOX. Below, check out all the performances from the episode, including an original song by GLEE's Darren Criss, "This Time."

The musical comedy follows a group of ambitious and talented young adults in search of strength, acceptance and, ultimately, their voice.

Over the last five years, the series has followed a dynamic group of high school students from the halls of McKinley to the mean streets of New York City, as they embarked on LIFE AFTER high school. This season, after her humiliating failure as a TV actress, New Directions' original star, RACHEL BERRY (Golden Globe Award nominee Lea Michele), comes home to Lima to figure out what she wants to do next. Upon discovering that SUE SYLVESTER (Emmy Award winner Jane Lynch) has banished the arts at McKinley, Rachel takes it upon herself to reinstate and lead the GLEEclub. Meanwhile, BLAINE ANDERSON (Darren Criss), SAM EVANS (Chord Overstreet) and WILL SCHUESTER (Matthew Morrison) have all found surprising new gigs in Ohio. Throughout the season, other alumnae also will return to McKinley.

Since its debut, GLEE has become a bona fide cultural phenomenon, received prestigious honors, including a Golden Globe Award and a Peabody Award, and singlehandedly made GLEE clubs cool again. The series boasts critical acclaim, a die-hard fan base, two Grammy Award nominations, two Platinum and five Gold albums, more than 53 million songs and more than 13 million albums sold worldwide, two sold-out concert tours, a 3-D movie, four Emmy Awards and three Golden Globes, including the award for Best Television Series - Comedy or Musical. The series reached its milestone 100th episode this past season with a memorable rendition of the hit that put the show on the map, "Don't Stop Believin'."
