Ringo Starr is back at work at Abbey Road studios in London for the first time since his treatment for alcohol abuse, and all he had to do was act naturally. "Ringo looked terrifically healthy and well when he arrived at Abbey Road. He was bright-eyed and very entertaining all day," said country singer Buck Owens. The former Beatle recorded a new version of his 1965 hit, "Act Naturally," with Owens, who wrote the song. Starr, 48, and his wife, 38-year-old actress Barbara Bach, spent five weeks undergoing treatment at a clinic in Arizona last year. The Owens-Starr duet will be the title track of an album to be released this summer. "Ringo must be the most down-to-earth famous person I have ever met," Owens said. "I know a lot of people who have had his kind of problems. But it is not everyone who has the intestinal fortitude to stand up and tell the world: `I've got a problem and I'm going to get some help."'
