From the management of Leon Russell:
Leon Russell has postponed all upcoming tour dates from now through Sept 18th. He is scheduled to have surgery this week in Nashville and will be recuperating for the next several weeks.
We here at the Peacemaker wish Leon a speedy recovery and are optimistic for his full recovery. We'll be making an announcement in the coming days about our replacement for Leon Russell's time slot at the festival.
Thanks for your understanding in this matter.
