Lyrics:

[Words and Music by Otis Blackwell and Elvis Presley]

You know I can be found
Sittin' home all alone
If you can't come around
At least please telephone
Don't be cruel to a heart that's true

Baby, if I made you mad
Somethin' I might have said
Please forget my past
The future looks bright ahead
Don't be cruel to a heart that's true
I don't want no other love
Baby, it's still you I'm thinkin' of, mmm

Don't stop thinkin' of me
Don't make me feel this way
Come on, let me hear you love me
You know what I want you to say
Don't be cruel to a heart that's true
Why should we be apart
I really love you, baby
Cross my heart

Let's walk up to the preacher
And let us say I do
Then you'll know you'll have me
And I know that I'll have you
Don't be cruel to a heart that's true
I don't want no other love
Baby it's still you I'm thinkin' of

Don't be cruel to a heart that's true
Don't be cruel to a heart that's true
I don't want no other love
Baby, it's still you I'm thinkin' of
