SING ME A RAINBOW
Words & Music by Shel Silverstein
Copyright © 1972 / Evil-Eye Music Inc., NY

Josie, it's been a long hard day
Down the road to where it at.
I must have lost my way.
When I got there, they said I was too late.
Now you're the only one can get me straight.

So won't you sing me a rainbow, Josie. Roll me a song.
Just tonight, make it right, 'cause it's been wrong for, oh, so long.
There's lots of shades of darkness, Josie, deep inside a man,
So sing me a rainbow if you can.

The train I went to meet had come and gone.
Seems like I spend all my time gettin' off and gettin' on.
I sold my mind and gave my dreams away,
And tomorrow I'll start lookin' 'round for yesterday,
But til then...

Sing me a rainbow, Josie. Roll me a song.
Just tonight, make it right, 'cause it's been wrong for, oh, so long.
There's lots of kinds of hunger, Josie, you don't understand,
So sing me a rainbow if you can,
If you can, if you can,
Sing me a rainbow if you can.

[Recorded by Dr. Hook and the Medicine Show, "Doctor Hook."]
