[Verse 1: Willie Nelson]
Crazy, I'm crazy for feeling so lonely
I'm crazy, crazy for feeling so blue

[Verse 2: Paul Anka]
And I knew, you'd love me as long as you wanted
And then someday, you'd leave me for somebody new

[Verse 3: Paul Anka & Willie Nelson]
Worry, why do I let myself worry?
Wondering, what in the world did I do?

[Chorus: Willie Nelson & Paul Anka]
And I'm crazy, for thinking that my love could hold you
I'm crazy for trying and crazy for crying
And I'm crazy for loving you

[Instrumental Break]

[Verse 3: Willie Nelson & Paul Anka]
Worry, why do I let myself worry?
Keep on wondering, what in the world did I do?

[Chorus: Willie Nelson & Paul Anka]
Crazy, for thinking that my love could hold you
Crazy for trying, crazy for crying
Crazy for loving, loving you
