You're Going to Lose That Girl

"You’re going to lose that girl, you’re going to lose that girl.
If you don’t take her out tonight, she’s going to change her mind,
And I will take her out tonight, and I will treat her kind.
You’re going to lose that girl, you’re going to lose that girl.
If you don’t treat her right, my friend, you’re going to find her gone,
‘Cos I will treat her right, and then you’ll be the lonely one..."

-The Beatles
