One of my favorite Toby Keith stories...
When Toby was starting out, he played the TLO Circuit. In the music biz, that's Texas-Louisiana-Oklahoma, mostly Oklahoma, NE Texas and NW Louisiana. There are some absolute dives in that part of the world.
Remember that scene in The Blues Brothers where they played a bar with chicken wire in front of the stage? Well, there are bars like that on the TLO circuit.
Bar fights are not uncommon. Whole bar fights do rarely happen, but they do.
Toby had just started to gain a little traction, enough to hire a manager, but he still was playing the circuit. One night, the bar they were playing erupted into a full bar fight. The manager is trying to get the band out of there, so they all head for the door. Toby, being a big guy, led the pack and the manager figured the safest place was behind Toby.
Some idiot was dumb enough or drunk enough to sucker punch Toby Keith.
The manager said Toby grabbed the guy with one hand and beat him with the other. The guy was screaming he'd had enough, when Toby stopped just long enough to look at the guy and tell him, "I'll let you know when you've had enough".
Then he hit him again, put the guy's lights out and dropped him like a sack of potatoes...
