The Beatles song you were never intended to hear came into the spotlight this week.

Paul McCartney waited 41 years to announce that he plans to release the 1967 track"Carnival of Light" to the public. These 14 minutes of unadulterated experimentation was recorded at Abbey Road studios and the Beatles feared the mainstream.
While recording in a late '60s daze, McCartney, just completely out of his mind, reportedly said: "Just wander round all of the stuff and bang it, shout, play it. It doesn't need to make any sense." The improvised piece includes distorted guitar, organ sounds, gargling and shouts of "Barcelona!" and "Are you all right?" from McCartney and John Lennon.

The band played the recording for an audience only one time -- at an electronic music festival in London.

When compiling songs for the comprehensive Anthology in the early '90s, McCartney's bandmates refused including the mystery song.

Why deny us this treasure from the beginning? It's not like we ever doubted the Beatles' spirit for experimenting. The next step for the jovial Beatle: acquiring permission from Ringo Starr and the widows of Lennon and Harrison. I wish him luck.
