All I know is something like a bird
within her sang
All I know she sang a little while
and then flew on
Tell me all that you know
If you hear that same sweet song again
Laugh in the sunshine
cry in the dark
through the night
Don't cry now
First performance: February 19, 1971, at the Capitol Theater in Port Chester, NY. "Bird Song" appeared in the third spot in the second set, following "Johnny B. Goode," and preceding "Easy Wind." Also premiered in the show was "Deal." The song remained in the repertoire steadily through September of 1973, then was dropped until September of 1980, after which it remained in steady rotation.
Hunter includes the dedication "...for Janis" with the lyric as it appears in Box of Rain. He also lists the title as "Birdsong" (all one word).
