WHILE MY GUITAR GENTLY WEEPS
(words & music by George Harrison)
I look at you all see the love there that's sleeping
While my guitar gently weeps
I look at the floor and I see it need sweeping
Still my guitar gently weeps
I don't know why nobody told you
how to unfold your love
I don't know how someone controlled you
they bought and sold you
I look at the world and I notice it's turning
While my guitar gently weeps
With every mistake we must surely be learning
Still my guitar gently weeps
I don't know how you were diverted
no one alerted you
I don't know how you were inverted
you were perverted too
I look at you all see the love there that's sleeping
While my guitar gently weeps
I look at you all
Still my guitar gently weeps
From the Wikipedia entry on George Harrison:
George Harrison, MBE (25 February 1943 – 29 November 2001) was an influential English rock guitarist, singer, songwriter, author and sitarist best known as the lead guitarist of The Beatles. Following the band's demise, Harrison had a successful career as a solo artist and later as part of the Traveling Wilburys super group where he was known as both Nelson Wilbury and Spike Wilbury.* He was also a film producer, with his production company Handmade Films, involving people as diverse as Madonna and the members of Monty Python. From an initial exposure whilst a member of the Beatles, he maintained a high public profile regarding his religious and spiritual life.
Here's something else that's pretty incredible: Jake Shimabukuro plays "While My Guitar Gently Weeps" on a ukulele!
*In 1969 Harrison wrote a song called Badge with Eric Clapton, Jack Bruce, and Pete Brown which subsequently appeared on a Cream album. He was credited as L'Angelo Misterioso, probably to avoid contractual complications.
