This week for the RTX Sunday Video we're celebrating the birthday of Johnny Cash! It was hard to decide which song to feature for this special occasion but this is one of my favs plus it pushes the edge of what's appropriate for KNUE (or a rap song) so remember friends "Lay off that whiskey, let that cocaine beeeeee" -- here's "Cocaine Blues."
