The Concert for Bangladesh was the name for two benefit concerts organised by George Harrison and Ravi Shankar, held at noon and at 7 PM on August 1, 1971, playing to a total of 40,000 people at Madison Square Garden in New York City. The concert was organised to fund relief efforts for refugees from East Pakistan (now Bangladesh) following the 1970 Bhola cyclone and atrocities during Bangladesh Liberation War. The event was the first ever benefit concert of such a magnitude. It featured a supergroup of performers that included Ravi Shankar, Bob Dylan, Eric Clapton, George Harrison, Billy Preston, Leon Russell, Badfinger, and Ringo Starr.
https://en.wikipedia.org/wiki/The_Concert_for_BangladeshI 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 needs 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
You were perverted too
I don't know how you were inverted
No one alerted you.
I look at you all see the love there that's sleeping
While my guitar gently weeps
Look at you all . . .
Still my guitar gently weeps
