I must be going My heart is showing 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 (repeat verse 1) If I don't leave I'll be sorry What will my Mary say?
