Nigel, here are the lyrics from the site you linked to.

(I didn't syllabicate it here the way it would be done in sheet music or the way it's done in the lyrics Sonja posted above, but making "blues" into a 2- or 4-syllable yodel, "sigh" into about 6 syllables, etc., are key to the song.

LOVESICK BLUES
by Irving Mills and Cliff Friend
As sung by Hank Williams

I got a feelin' called the blues, oh, lawd,
Since my baby said good-bye.
Lawd, I don't know what l'll do,
All I do is sit and sigh. oh, lawd,
That last long day she said goodbye,
Well, Lawd, I thought I would cry.
She'd do me, she'd do you,
She's got that kind of lovin'.
Lawd, I love to hear her
When she calls me "Sweet Daddy,"
Such a beautiful dream!
I hate to think it all over.
I lost my heart, it seems.
I've grown so used to you* somehow,
Well, I'm nobody's sugar daddy now,
And I'm lonesome. I got the lovesick blues.

I'm in love, I'm in love with a beautiful gal,
That's whats the matter with me.
Well, I'm in love, I'm in love with a beautiful gal,
But she don't care about me.
Lawd, I tried and tried to keep her satisfied,
But she just wouldn't stay.
So now that she is leavin',
This is all I say:

Note: The underscored words/syllables are multi-syllabic yodels.

*Note the change from the 3rd person to the 2nd person here. Patsy Cline sings "that man" instead of "you."
