(Roy Turk - Fred E. Ahlert)

I don't know why I love you like I do
I don't know why I just do
I don't know why you thrill me like you do
I don't know why you just do.

You never seem to want my romancing
The only time you hold me is when we're dancing
I don't know why I love you like I do
I don't know why I just do.

(I don't know why I love you like I do
I don't know why I just do
I don't know why you thrill me like you do
I don't know why you just do.

--- Instrumental ---

I don't know why I love you like I do
I don't know why I just do.

I don't know why I just do...
