I must be going (Don't go)
My heart is showing (Don't go)
I better hurry away
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
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 break in two
I must be going (Don't go)
My heart is showing (Don't go)
I better hurry away
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)
