I have been so Excited ever since I read this the other day in the Local Newspaper....If you're a Beatlemaniac, then you're going to love this: Paul McCartney intends to release an experimental track the group recorded but was never played for the public.
The 14 minute song, called Carnival of Light, was recorded by The Beatles in 1967.
During the session McCartney suggested that the other band members "just wander round all of the stuff and bang it, shout, play it. It doesn't need to make sense."
"I like it because it's The Beatles free," he told the BBC.
McCartney added, "The time has come for it to get its moment."
However, before releasing it he'll still have to get the OK from Ringo Starr and the widows of John Lennon and George Harrison.  WOW ... 41 years ago... It seems like  ... Yesterday!

Wikipedia descibes:  Carnival of Light" is an unreleased experimental piece by The Beatles. It was recorded on January 5, 1967, after the vocal overdubbing sessions for "Penny Lane". The track was created for The Million Volt Light and Sound Rave, an event held at the Roundhouse Theatre on January 28 and February 4, 1967. Some reports indicate that it is around fourteen minutes long.[1] and Paul McCartney has said it was around fifteen minutes. In The Complete Beatles Chronicle it's listed as lasting 13 minutes and 48 seconds.  http://en.wikipedia.org/wiki/Carnival_of_Light 

It will be FUN to see what this release from the 'Fab 4' will be like! There are so many of the Beatles songs that Just make you Happy... filled with good words, love and tears ... it is said ... The songwriting partnership of John Lennon and Paul McCartney, usually referred to as Lennon/McCartney, is one of the best-known and most successful musical collaborations of all time. In an agreement reached early in their partnership, the pair agreed to use the shared credit Lennon/McCartney on all songs written alone or in tandem for The Beatles. Their output constitutes the bulk of The Beatles' catalogue. Lennon, with his cynical edge and knack for introspection, and McCartney, with his storytelling optimism and gift for melody, complemented each other. Lennon and McCartney formed a critically acclaimed and commercially successful partnership writing songs for The Beatles and other artists.  http://en.wikipedia.org/wiki/Lennon/McCartney

It will be FUN to see and Hear what the Carnival of Light will brighten!
