Green Finch and Linnett Bird

Green finch and linnet bird
Nightingale, blackbird
How is it you sing?
How can you jubilate
Sitting in cages
Never taking wing?
Outside the sky waits
Beckoning, beckoning
Just beyond the bars
How can you remain
Staring at the rain
Maddened by the stars?
How is it you sing
Anything?
How is it you sing?
My cage has many rooms
Damask and dark
Nothing there sings
Not even my lark
Larks never will, you know
When they're captive
Teach me to be more adaptive
Ah
Green finch and linnet bird
Nightingale, blackbird
Teach me how to sing
If I cannot fly
Let me sing
