Spring is sprung, the grass is riz

There are so many beautiful spring flowers now all around us and today was a fantastically sunny day; I thought of the doggerel we were taught as kids:

Spring is sprung, the grass is riz
I wonder where the birdies is
The little bird is on the wing
Ain't that absurd
The little wing is on the bird!

I always wondered who wrote it but apparently we do not know - it is attributed to that wonderfully talented author Anon.

I gather one version is called The Budding Bronx and goes as follows:



Der spring is sprung
Der grass is riz
I wonder where dem boidies is?

Der little boids is on der wing,
Ain't dat absoid?
Der little wings is on de boid!

Anyone out there know anymore about this?
