-- An ailing back has forced Dolly Parton to postpone her U.S. tour, which was due to begin Feb. 28 in Minneapolis. Parton has been ordered to rest for six to eight weeks; she is hoping to reschedule the dates for late April and May. Parton's European tour, due to begin June 13 in Stockholm and run through a July 5-6 run at London's O2 Arena, is still on the books, according to Parton's publicist. Parton's new album, "Backwoods Barbie," arrives Feb. 26 on her own Dolly Records label.
