This is the tune that I remember playing on the piano as a kid. I can't remember is it is the whole tune though. Can anyone help me?

Doctor, Doctor, can you tell
What will make poor (Sally) well

She is sick and about to die
That will make poor (Johnny) cry

(Johnny), (Johnny), don't you cry
She'll get better by and by

When she comes all dressed in blue,
She will have a kiss for you

When she comes all dressed in white,
She will marry you tonight.
