What's behind the lyrics?

John Lennon and Elton John had become good friends along the 70s. They composed and played together several times live and in studio.In 1974, they also played together at the Madison Square Garden in New York, the city where John Lennon had been living for some time.
After Lennon's death, Elton John composed a song named Empty Garden as a tribute to his musician friend. The song became very popular in the eighties, also because of that.


If you read the lyrics you will perceive the imagery used by Elton John to tell us about his dead friend. It is sad but beautifully written as well. When you listen to it, you will probably feel moved like I do whenever I listen to it.

What happened here
As the New York sunset disappeared
I found an empty garden among the flagstones there
Who lived here
He must have been a gardener that cared a lot
Who weeded out the tears and grew a good crop
And now it all looks strange
It's funny how one insect can damage so much grain

And what's it for
This little empty garden by the brownstone door
And in the cracks along the sidewalk nothing grows no more
Who lived here
He must have been a gardener that cared a lot
Who weeded out the tears and grew a good crop
And we are so amazed we're crippled and we're dazed
A gardener like that one no one can replace
Chorus:
And I've been knocking but no one answers
And I've been knocking most all the day
Oh and I've been calling oh hey hey Johnny
Can't you come out to play

And through their tears
Some say he farmed his best in younger years
But he'd have said that roots grow stronger if only he could hear
Who lived there
He must have been a gardener that cared a lot
Who weeded out the tears and grew a good crop
Now we pray for rain, and with every drop that falls
We hear, we hear your name

Johnny, can't you come out to play in your empty garden
(Repeat Last Line And Fade)
