Lyrics of There's a bird on my windowsill

There's a bird on my windowsill, it's looking at meeeeeeeeeeeeeee,
There's a bird on my windowsill, it's distracting meeeeeeeeeeeeeee,

Fluffy black bird on my windowsill,
In my music lesson,
Distracting me,
And my friends.

Then the bird flies off, rears it's ugly head again and makes the kind of noises:
(adam trills on clarinet)

Bird on my windowsill
Bird on my windowsill
Bird on my windowsill
Bird on my windowsill
Bird on my windowsill
Bird on my windowsill
Bird on my windowsill
Bird on my windowsill
Bird on my windowsill
Bird on my windowsill
Bird on my windowsill
Bird on my windowsill
Bird on my windowsill
Bird on my windowsill
Bird on my windowsill
Bird on my windowsill

Bird on my
Bird on my
Bird on my
Bird on my
Bird on my
Bird on my

That damn bird!

Here it comes again!
