For a band that is so beloved and so obsessed over, there really are a ton of things that are still unknown about The Beatles. At the very least, there are many little-known facts about the Fab Four as well as what they did after the band broke up. This includes which Beatle claims he spoke to aliens and which ate a celery stick in the background of another famous band's song. There's even a lot to be discovered (or re-discovered, if you're one of The Beatles biggest fans) about their most famous songs.

Without a doubt, "While My Guitar Gently Weeps" is one of The Beatles' most famous songs off of their most famous album, "The White Album"... But did you know that it was almost a VERY different song?

"While My Guitar Gently Weeps" Was George's Song... And He Wasn't Happy At First

If you've ever heard Sir Paul McCartney being interviewed on The Howard Stern Show, you'd know that each of The Beatles got a chance to take the lead on their own song. Essentially, if they thought of the idea, they had the power to run with it. While it seems as though John Lennon and Paul McCartney were in control most of the time, both Ringo Starr and George Harrison got their moments to shine. As for "While My Guitar Gently Weeps"... well, that was George's moment to shine, according to a fascinating interview by UDiscoverMusic.

The truth is, "While My Guitar Gently Weeps" went through some very notable changes over the course of recording the song. The song we know and love is one of The Beatles' heaviest rock songs. It doesn't have the drug-addled whimsy or folk-nature of some of their other work. This is a rock song in the truest sense. But the original versions of George Harrison's song were far more 'tender', according to UDiscoverMusic. In these versions from July 1968, George Harrison was singing to his own guitar placing with only Paul McCartney in the background for harmony. While some have claimed that this version is the purest, it was not at all what George was after. It took two more vastly different recordings to get what he wanted, which is the song we all know.

Not only was the style of music changed over the course of these re-recordings, but the lyrics were altered as well. The song was originally inspired by the "I Ching", a book on ancient Chinese divination. In an interview, George Harrison said, "'While My Guitar Gently Weeps’ was just a simple study based on the theory that everything has some purpose for being there at that given moment. I was thinking that anything I see when I open a book, I’m going to write a song about. So I opened this book and I saw ‘gently weeps.’ I shut the book and then I started the tune."

While this provided a strong base for the song, he just wasn't feeling the original versions he had done with just Paul. So, with Paul's help, John and Ringo were brought in to make the song a little more energetic. While Goerge spent hours on the second major re-crafting of the song, he eventually scrapped all of his works.

It actually took another rock legend to come in and help George, Paul, Ringo, and John get this song right.

Enter Eric Clapton

In 1964, Eric Clapton and his band The Yardbirds helped to support The Beatles as they were coming up. In the process, they made friends with Eric. George was especially close to Eric, who is best known for his songs "Cocaine", "Layla", "Lay Down Sally", "and "I Shot The Sheriff".

While Eric was brought in to help George with "While My Guitar Gently Weeps", the "Tears From Heaven" musician was reluctant.

In an interview with Guitar Player back in 1987, George claimed that Eric Clapton didn't want to help record "While My Guitar Gently Weeps" as he didn't want to be on a Beatles album.

"He said, 'Oh, no. I can’t do that. Nobody ever plays on The Beatles’ records.' I said, 'Look, it’s my song, and I want you to play on it.' So Eric came in, and the other guys were as good as gold – because he was there. Also, it left me free to just play the rhythm and do the vocal. So Eric played that, and I thought it was really good. Then we listened to it back, and he said, 'Ah, there’s a problem, though; it’s not Beatley enough' – so we put it through the ADT, to wobble it a bit."

George's assistant at the time, Chris Thomas, was put in charge of "waggling the oscillator" on the song, given the rock song a little bit of the Beatles flavor.

With Eric Clapton's help, the song found the style and voice that George Harrison (who still sings the lead vocals on the track) had intended for it. And, boy, are we ever thankful for that!
