Lyrics:

(LennonMcCartney) I got something to say that might cause you pain If I catch you talking to that boy again I'm gonna let you down And leave you flat Because I told you before, oh You can't do that Well, it's the second time I've caught you talking to him Do I have to tell you one more time, I think it's a sin I think I'll let you down (Let you down) Leave you flat (Gonna let you down and leave you flat) Because I've told you before, oh You can't do that Everybody's green Cos I'm the one who won your love But if they'd seen You're talking that way they'd laugh in my face So please listen to me, if you wanna stay mine I can't help my feelings, I'll go out of my mind I'm gonna let you down (Let you down) And leave you flat (Gonna let you down and leave you flat) Because I've told you before, oh You can't do that, oh (You can't do that You can't do that You can't do that You can't do that You can't do that) Everybody's green Cos I'm the one who won your love But if they'd seen You're talking that way they'd laugh in my face So please listen to me, if you wanna stay mine I can't help my feelings, I'll go out of my mind I'm gonna let you down (Let you down) And leave you flat (Gonna let you down and leave you flat) Because I've told you before, oh You can't do that
