The reason the general public likes BP so much is...it has a VERY recognizable and oft-repeated chorus which any idiot can remember and holler along with...it's loud and aggressive, good for drunks or just plain enthusiastic people to bellow out...it has the phrase "God damn them all!" in it, and most people enjoy yelling that (although a few are offended by it).

What more do you need for a popular bar song?

Most of Stan Roger's stuff veers between macho and maudlin...sometimes both at the same time...but for macho and maudlin stuff some of it is pretty damn good. ;-)
