A Man Doesn't Know - Damn Yankees

[JOE]
A man doesn't know what he has until he loses it,
When a man has the love of a woman he abuses it,
I didn't know what I had when I had my old love,
I didn't know what I had 'till I said, "Goodbye, old love!"
Yes, a man doesn't know what he has 'til it is no longer around
But the happy thought is
Whatever it is he's lost, may some day once again be found!
