Sesame Street - High, Middle, Low lyrics

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
