A part of the musical line-up for the 71st annual Bluebonnet Trails and Festival, hosted by the Ennis Garden Club, has been announced by the City of Ennis. And topping the list is Slippery When Wet. Also known as the Ultimate Bon Jovi Tribute Band, the musicians are inspired by the 1980s hard rock band popular originally among the so-called “MTV generation” of teenage fans.
