Former LED ZEPPELIN frontman Robert Plant and guitarist Jimmy Page have reportedly given "thumbs up" to Dolly Parton's bluegrass cover of "Stairway To Heaven", which is featured on Parton's upcoming album, Halos And Horns. Dolly's version of the classic rock anthem was changed to incorporate her own ad-libs, which required her to get approval from the original writers and publishers. "I was scared to death to send it to Robert Plant and Jimmy Page," said Parton. "They sent word back that it was fine and they loved it. In fact, Robert Plant said he'd always thought of it as a spiritual song, and he was thrilled we'd used a choir on it, because he thought about that, too. If they like it, that's most important to me. But I do hope the public will accept it too. I even hope they love it."
