The Boo-Boo bird is an inhabitant of the imagined land of Y'Hup. The bird cannot be seen, and is identified solely by the sound it makes.
I am a Boo-Boo bird
Of all the birds I am the most absurd
I have no head, I have no tail, I have no wings
I have no legs, I have no body
I'm invisible
And when all the people see me
High in the sky
The Boo-Boo bird, they say
Is on his way
How do they know that I'm the Boo-Boo bird?
I'll tell you how
I go "Boo-Boo"
I go "Boo-Boo"
People are glad to see me come
They say I am a bird of good omen
I am a Boo-Boo bird
I go "Boo-Boo"
The Boo Boo Bird was written by Ivor Cutler.
The Boo Boo Bird was produced by George Martin.
