Buffalo Springfield

Listen to my bluebird laugh.
She can't tell you why.
Deep within her heart, you see,
She knows only crying.
Just crying.
There she sits, a lofty perch.
Strangest color blue.
Flying is forgotten now.
Thinks only of you.
Just you.
So, get all those blues,
Must be a thousand hues.
And be just differently used.
You just know.
