US rock star Gregg Allman has been forced to cancel a series of tour dates for health reasons.
The singer's performance at the AmeriServ Flood City Music Festival in Pennsylvania on Saturday may have been one of the last chances for fans in the region to see Gregg and his band, The Bridge.
Gregg, who was married to Cher and had a son with her, was a founding member of the Allman Brothers Band who had hits with Ramblin' Man, Midnight Rider, Jessica and Ain't Wastin' Time No More.
The 64-year-old - who suffers from an upper respiratory condition - will reportedly require several days of hospital treatment and four to six weeks of bed rest.
Tour dates between August 26 and September 15 have been cancelled.
The Bridge are apparently splitting up at the end of the year because of financial difficulties.
Festival spokeswoman Shelley Johansson said: "It just makes me more grateful that he was here and put on such a wonderful performance."
