Dolly Parton’s return to the Ryman is in high demand.  Tickets for the iconic singer’s benefit concert at the historic venue sold out in record time on Saturday.  The show sold out within one day, making it the fastest-selling event in the Ryman’s history.  Dolly’s concert on July 31st will mark her first time performing at the theater in 13 years.  The proceeds will benefit the Dustin Wells Foundation’s fund for a local music school.
