"Cheeseburger" and "Margaritaville" are probably the most recognizable Buffet tunes. I do the Wiki list that Bernie referred to ... minus 'Let's Get Drunk ...' I only get to do these tunes for the CC pool opening parties although, I'll be doing a night at a 3 day Margarita Festival in August, and that's the only other venue , for me, that calls for Buffet tunes.
