The song Mind Gardens [Alternate Version] is performed by The Byrds .
Once upon a time
There was a garden on a high hill
Standin' green and blossomin' against the sea
And there the sun came and the rain pourin' down
The garden grew and splattered bits of color on the ground
And took shape and symmetry all around
There came winds, driven and howling
There came snow
And I feared for the garden, so I built a wall
And another, roofed it over
Thick and strong
I kept it from the slings and arrows of outrageous fortune
But when the sun came and the gentle rain of spring
They could not find the garden behind those walls
It would have died safely, securely died
But as I watched and as I learned
I tore the walls down, the garden still lives
