It happened about 1:55 Tuesday morning outside Hogan's Place as the bar was closing.
Police said Brian Minugh who recently changed his name to Bam Chevelle, punched a female bartender then pushed her.
As others joined in to break up the altercation, police said Minugh stabbed one of them in the chest and the bartender in the thigh.
Minugh left the scene, but was caught before noon.
He now faces two counts of first degree assault, and one count of fourth degree assault.
The bartender and the other victim were taken to a local hospital.
