I must be going (don't go)
My heart is showing (don't go)
I better hurry awa-ay-ay-ay-ay
If I don't leave I'll be sorry
What will my Mary say?
Your lips are thrilling
My arms are willing
I know that I shouldn't stay-ay-ay-ay-ay
If I don't leave I'll be sorry
What will my Mary say?

What would I do if she should need me
And find me kissing you?
She's always trusted me completely
Her poor heart would bre-ea-eak in two

I must be going (don't go)
My heart is showing (don't go)
I better hurry awa-ay-ay-ay-ay
If I don't leave I'll be sorry
What will my Mary say?

If I don't leave I'll be sorry
What will my Mary say?

(Don't go)
(Don't go)
