The song, Two Birds On A Wire... Does nobody realize it ties to the book: I Know Why The Caged Bird Sings ?
Two Birds On A Wire Lyrics:
Two birds on a wire
One tries to fly away
And the other watches him close from that wire
He says he wants to as well
But he is a liar
I'll believe it all
There's nothing I won't understand
I'll believe it all
I won't let go of your hand
Two birds on a wire
One says c'mon and the other says "I'm tired"
The sky is overcast and I'm sorry
One more or one less
Nobody's worried
I'll believe it all
There's nothing I won't understand
I'll believe it all
I won't let go of your hand
Two birds of a feather
Say that they're always gonna stay together
But one's never going to let go of that wire
He says that he will
But he's just a liar
Two birds on a wire
One tries to fly away and the other
Watches him close from that wire
He says he wants to as well, but he is a liar
Two birds on a wire
One tries to fly away and the other

What I "I Know Why The Caged Bird Sings" About:
The poem describes the opposing experiences between two birds: one bird is able to live in nature as it pleases, while a different caged bird suffers in captivity. Due to its profound suffering, the caged bird sings, both to cope with its circumstances and to express its own longing for freedom.
