This piece is an ode to the 1952 jazz standard “Lullaby Of Birdland”, in which the title refers to Charlie "Bird" Parker and the Birdland jazz club named after him. Many vocal and instrumental performers, including Ella Fitzgerald, Sarah Vaughan, and more recently Amy Winehouse have recorded the song. Here’s the key excerpt:
Have you ever heard two turtle doves
Bill and coo, when they love?
That's the kind of magic music we make with our lips
When we kiss
