Lyrics of High, middle, low

Herbert birdsfoot:

Oh, i can only sing the high part.
It's the only part i know.
And when i sing the high part,
This is how i go:
La, la-la-la-la-la-la, la
La, la-la-la-la-la-la.

Ernie:

I can only sing the middle.
It's the only part i know, i know.
And when i sing the middle part,
This is how i go:
La, la-la-la-la-la-la, la
La, la-la-la-la-la-la.

Bert:

I can only sing the low part, low part,
It's the only part i know, i know.
And when i sing the low, low part,
This is how i go.
(that's beautiful, bert!)
La, la-la-la-la-la, la-la, la-la,
La, la-la-la-la-la-la.

Sung by all 3 together:

When we put them all together
I am sure you will agree, agree,
The whole sounds better than the parts
As you can plainly see.
La, la-la-la-la-la, la-la, la-la,
La, la-la-la-la-la-la, la la la la.
