"East Bound and Down" is a song written by Jerry Reed for the soundtrack of "Smokey and the Bandit" (1977). The lyrics tell the basic plot of the movie - a 28-hour round trip run from Atlanta to Texarkana and back - to illegally deliver 400 cases of Coors beer for a post-race party.  The definitive chase scene features Bo “Bandit” Darville (Burt Reynolds) driving an iconic black-and-gold Pontiac Trans Am to distract law enforcement while his partner Cletus “Snowman” Snow (Jerry Reed) hauls the bootlegged shipment.  The high-speed pursuit stretches across the American Southeast and showcases some of cinema’s most famous practical car stunts.  For Jeremiah P - who loves the Trans Am.
