"Sing 'Em Good My Friend" is a new song from Kenny Chesney
The song tells the story of an old man with a dying wife selling his guitar to a younger musician, while telling him, "I left some songs in this guitar/Sing 'em good my friend."
The guitar is the last of the old man's possessions he's selling, presumably to pay for his wife's medical bills.
It's another track on his upcoming album"Welcome To The Fishbowl", which drops Tuesday.
