Comedian Steve Byrne, the star and creator of Sullivan and Son. gets laughs by making fun people based on the types of music they listen to; he also likes to have audience members join him on stage so he can create his own boy band. Expect a lively, interactive show when Byrne performs tonight at 8 at the Improv, where he has performances scheduled through Sunday. Tickets are $23 to $30. (Niesel)
