paul simon and wes anderson go cuckoo in april

From Sounds of Silence, Simon and Garfunkel’s second album, released on January 17, 1966. It had also appeared prior to this on a UK-only release, The Paul Simon Songbook, in August 1965.

The song bears a structural resemblance to a traditional English rhyme, “Cuckoo, cuckoo, what do you do?”, a phenology of the Common Cuckoo from April to September:

Cuckoo, Cuckoo, what do you do?
“In April I open my bill;
In May I sing night and day;
In June I change my tune
In July far far I fly;
In August away I must.”
Cuckoo, Cuckoo!

This choral version of the rhyme was featured on the soundtrack to Wes Anderson’s 2012 film, Moonrise Kingdom:
