Bob Dylan and Willie Nelson have spent the early part of the summer on a joint tour of minor league baseball stadiums. Similar to last years summer outing, the two-American icons have used their double bill to collaborate onstage when the opportunity presents itself. Yesterday proved to be one such opportunity as Nelson joined Dylan onstage for a version of Hank Williams You Win Again at his annual 4th of July Picnic. Before this tour, Dylan last performed the cover at the Bonnaroo Music Festival on June, 11 2004 (a lifetime ago given The Bards busy tour schedule). Tomorrow, Nelson and Dylans joint outing will continue at Tulsa, OKs Drillers Stadium.
