Country legend Merle Haggard was forced to cancel his scheduled appearance at the Red River Music Festival recently in Texas because of a gum infection. Festival organizers opted to postpone the show for two weeks. "There's no sense in the festival going on without Merle," says a festival representative." PLUS! Be on the look out for the second Merle Haggard autobiography to hit the bookstore shelves in the next year or so. The legendary singer explains that the first book entitled Sing Me Back Home, released in 1981, was too distorted. The new book, The Running Kind, is slated for a November, 1999 release.
