Song Horton's singing

Remember the song Horton was trying to sing? All he did was, "Hut-Sut Rawl sitting on the rillerah and a so and so on." The actual song is called the "Hut-Sut Song" (aka "A Swedish Serenade") and the full lyrics is:

The Hut-Sut Song
Horace Heidt
Words and music by Leo V. Killion, Ted McMichael & Jack Owens

In a town in Sweden by a stream so clear and cool
A boy would sit and fish and dream when he should have been in school.
Now, he couldn't read or write a word but happiness he found
In a little song he heard and here's how it would sound;

Hut-Sut Rawlson on the rillerah and a brawla, brawla sooit,
Hut-Sut Rawlson on the rillerah and a brawla sooit.
Hut-Sut Rawlson on the rillerah and a brawla, brawla sooit,
Hut-Sut Rawlson on the rillerah and a brawla sooit.

Now the Rawlson is a Swedish town, the rillerah is a stream.
The brawla is the boy and girl,
The Hut-Sut is their dream.

Hut-Sut Rawlson on the rillerah and a brawla, brawla sooit.
Hut-Sut Rawlson on the rillerah and a brawla sooit.
