I'm pretty sure it's "Mama, just killed a man."
Punctuation... saves lives AND stops the innocent from going to jail ;D
Well yeah, it completely changes the meaning without the comma, haha.
yeah, this actually took me a few seconds to understand because i didn't know what it was quoting at first.
Put a gun against his head,
pulled my trigger now he's dead
OOOOOHHHHH, didn't mean to make you cry,
He took the midnight train goin' anywhere
If I'm not back again this time tomorrow.
Mama, life had just begun.
But now I've gone and thrown it all away!
