Evansville Firefighters wrapping up a call, Wednesday night, were surprised to spot a familiar face nearby. According to the department, Station 8 and 10 crew members ran into ZZ Top's guitarist and lead vocalist Billy Gibbons. The rock star was checking out a hot rod in a garage next door to where EFD was finishing a call. Gibbons took the time to snap a photo with the firefighters. ZZ Top was set to play a concert in Evansville this week but had to cancel because of a band member's health concerns.
