On this edition of Roker Radio I'm joined by none other than John Popper from Blues Traveler! We'll talk about their new album "Traveler's Blues," their new tour, his broken bones, musical influences, what almost got him kicked off Saturday Night Live, and much, much more! Hear their next single "Sittin' on the Top of the World!" Plus find out how you can win tickets to their show in Island Lake, Il.  August 21st!
