Years ago I played guitar with bands doing gigs on what I lovingly refer to as the "Juke Joint" circuit. Little dives, honky tonks and watering holes catering to the crowd that works hard, and parties harder.
In many of these "joints", a tequila induced transformation would take place somewhere on the south side of midnight, and invariably, the warm fuzziness of friends having fun would be replaced by feuds and fisticuffs.
As a guitar player on stage I did my best to avoid these late night free-for-alls and just play the gig while the "joint" started rockin', but there were occasions when landing in the middle of a brawl was simply un-avoidable.
