By day, Bob Quinn is executive vice president of finance and administration for the Brewers.

At night -- and sometimes in the middle of the afternoon -- he wields a Telecaster like a hellcat ...

Quinn joins his friends from the band Hoi Polloi during the band's Summerfest set, which begins at 12:30 p.m. Thursday on the U.S. Cellular Stage.

Hoi Polloi is described a versatile five-piece rock and reggae band that plays original music as well as a mix of classic and contemporary rock covers.

The group performed as the "house band" at the Brewers Winter Warm-Up this past off-season and also appears at popular live venues. The band's Web site is hoipolloilive.com.
