Another often misquoted line. I’ve never seen the movie myself but I understand ‘Play it again Sam’, is actually only ‘Play it Sam’, or words to that effect.

“A lot of people get confused and they bruise
Real easy when it comes to love.
They start puttin’ on a shoe and walkin’ out
And singin “boy, I think I had enough”.

Just because
She makes you feel wrong,
She don’t mean to be mean
Or hurt you on purpose, boy,
Take a tip and do yourself a little service..
Take a mountain…turn it into a mole.
Just by playing’ a different role.
Yeah, by playing a different role.”
