I had to vote Foghat just because that album had many classic FM radio cuts I remember from my adolescent years. But that Pat Travers album contains one of my all-time favorite "party" cuts. In fact "Boom Boom Out Go The Lights" is the only song I know by the band but that song and George Thorogood's "One Bourbon, One Scotch And One Beer" are two of my all-time favorite live tracks and definitely got cranked at every kegger and pig roast I attended in college.
