Darius Rucker and Eric Church will be joining Dierks Bentley at a concert following his fourth annual Miles and Music for Kids celebrity motorcycle on Oct. 11 in Nashville. All proceeds from the event will benefit the Monroe Carell Jr. Children's Hospital at Vanderbilt, a Children's Miracle Network hospital. Bentley is working with Nationwide Insurance, the Children's Miracle Network and CMT's pro-social initiative, CMT One Country, to expand the Miles and Music for Kids event to six cities in 2009 and 2010 with all proceeds benefiting Children's Miracle Network hospitals in those areas. In the three previous years, the event has raised more than $500,000 for the children's hospital in Nashville. Tickets for the Nashville event go on sale on Saturday (Aug. 15) via Ticketmaster. Tickets for the ride, concert and commemorative T-shirt are $50. Tickets to the concert at Riverfront Park in downtown Nashville are $20.
