FOX’s pre-holiday episode of Glee hit all the right notes, featuring several great performances that struck a chord with viewing audiences. Not only did we get two fabulous solo performances in the show’s renditions of “Papa Don’t Preach” and “True Colors,” but Eve was the guest star! Even without all this flash and sizzle, however, the latest episode of Glee would still be its best…and it’s all because of John Lennon.

The heart-tugging “Imagine” number was definitely the highlight of the episode, featuring beautiful vocals and lots of eye-dampening moments. The video above is audio only, but it’s still great even without the visual. Lennon’s most famous song still has a huge effect.

Originally released in 1971, “Imagine” is every bit as poignant today as it was when it was first written as an anti-war song (Vietnam). Because of what was believed to be its Communist message, the song was fairly controversial; it wasn’t even released in the UK as a single until 1975. A 2002 Guinness World Records poll lists this song as Britain’s second favorite single of all time (“Bohemian Rhapsody” took top honors).
