Will ‘Glee’s’ final season be the best one yet?

Get ready to say goodbye to “Glee.”

The beloved musical dramedy kicks off its farewell tour with a 13-episode run beginning Friday, Jan. 9 — but before “gleeks” get to see Rachel Berry’s (Lea Michele) full rendition of “Let It Go” (as shown in the new trailer above), let’s take a look back at some of the show’s most memorable performances.

‘Don’t Stop Believing’ (Season 1)

No “Glee”-related countdown is complete without the set that started it all. Featuring all of the original players — including a fresh-faced Finn Hudson (Cory Monteith) — the glee club hit the McKinley High School stage and put a new spin on Journey’s iconic track.

‘Dream On’ (Season 1)

“Glee” may be known for its show-stopping musical numbers, but its lengthy list of A-list guest stars is also notable. Case in point — Neil Patrick Harris’ turn as Will Schuester’s (Matthew Morrison) arch-nemesis Bryan Ryan. The dueling duo hit some serious high notes during their rendition of the Aerosmith classic.

‘Forget You’ (Season 2)

The show raised the bar during its sophomore season by enlisting Gwyneth Paltrow to play substitute teacher Holly Holliday. CeeLo Green’s hit never sounded so Goop-y.

‘Teenage Dream’ (Season 2)

It’s easy to see why viewers and Kurt (Chris Colfer) fell in love with Blaine Anderson (Darren Criss) in year 2. The peppy performance of Katy Perry’s smash single is what “Teenage Dreams” are made of.

‘I Will Always Love You’ (Season 3)

Lighthearted comedy or not, “Glee” knows how to tug on the heartstrings. Following an emotional moment between Mercedes Jones (Amber Riley) and Sam Evans (Chord Overstreet), the vivacious beauty expresses her feelings through Whitney Houston’s megahit. Grab the Kleenex — you’ll need it for this one.

‘We Are the Champions’ (Season 3)

The “Glee” gang bid McKinley High farewell at the end of the third season. But before venturing off into the sunset, Mr. Schuester’s favorite students thanked him (through song, of course) with Queen’s classic.

‘The Scientist’ (Season 4)

Breakups are rough, but no show handles them quite like “Glee.” Rachel, Kurt and company hit the stage for a super-solemn rendition of Coldplay’s “The Scientist,” ultimately putting a new spin (and sound) on conscious uncoupling.

‘Shout’ (Season 4)

The acclaimed series celebrates a milestone in the fourth season with its 500th song. Blaine and his pals channel the brothers from “Animal House’s” Delta Tau — to a lesser extent, mind you — with their rendition of the Isley Brothers’ “Shout.” If this performance doesn’t make you want to get up and dance, we don’t know what will.

‘Seasons of Love’ (Season 5)

The untimely death of Cory Monteith left the series’ fate up in the air. While the cast and crew did return for a fifth season, it wasn’t without paying tribute to the fallen “Quarterback.” With the help of the memorable song “Seasons of Love” from “Rent,” “gleeks” young and old honored their brother at his second home — McKinley High.

‘Pompeii’ (Season 5)

Despite a rough start, “Glee” was shining bright again by the season finale. Series vets, including Artie Abrams (Kevin McHale) and Brittany S. Pierce (Heather Morris), hit the streets of NYC for a vibrant performance of Bastille’s uber-catchy “Pompeii.”
