Georgia rockers Jackyl dropped the video Monday for "Screwdriver," the first single from its upcoming album "Best In Show," which is slated for an October 31st release on the Mighty Loud Entertainment imprint.  Check out the video below.  Formed in 1990, Jackyl have been performing their own special brand of Southern metal for more than two decades, achieving a reputation as one of the hardest working bands in the world.  As evidence of this hardworking mentality, the band holds two distinct Guiness World Records, one for the most concerts performed in a 24-hour period (21), and another for 100 gigs in just 50 days.  The band's frontman Jesse James Dupree also stars in "Full Throttle Saloon," a reality show set around the biker bar in Sturgess, South Dakota for which Dupree organizes the entertainment.
