The Beatles' classics have entertained music enthusiasts for decades, but could a new Beatles song be on the horizon?

Sir Paul McCartney tells the Associated Press that he feels the time is right for the public to hear "Carnival of Light," a 14-minute experimental song the group recorded in 1967 that was never released.

And this particular song is not your average Beatles classic. The AP says the track reportedly contains distorted guitar and gargling sounds -- and even includes McCartney and bandmate John Lennon shouting "Barcelona!" and "Are you all right?"

The legendary musician tells the news agency about the unconventional way in which the song was recorded.

While recording, he told his bandmates to "just wander round all of the stuff and bang it, shout, play it. It doesn't need to make any sense."

So why after all these years is McCartney pushing for the song's release?

The British artist simply states, "The time has come for it to get its moment."

In order to release the track, McCartney would still need to obtain permission from Ringo Starr and the widows of both Lennon and George Harrison.
