This is really simple. You make a deal with the bar that if the game ends up being at 6pm or later, the show will start sometime between noon and 3 (I don't know, solicit feedback here about whether people would want to F14 and then tailgate or have F14 be the tailgate. If the game is in the 11 or 11:30 slot, F14 will be immediately after the game.
Not sure what everyone would prefer for a 2:30 game, I'd lean towards pregame F14 being the tailgate vs. thinking anyone could commit to doing something at 6 after all day of pak'n and such.
Regardless, in any of those scenarios, your MysBar is getting a boost during the day and you're cleared out by evening for them to do whatever squawks do there.
