Suggesting that being a 67-year-old former Beatle no longer carries the cachet that it once did, the producers of Live With Regis and Kelly on Tuesday refused to allow Ringo Starr to perform a song from his new album, Liverpool 8, unless he cut it to less than three minutes. Starr's publicist, Elizabeth Freund, told the Associated Press Tuesday that the drummer/singer walked out of the studio after the show's producers refused to compromise by cutting back the chat time on the program. A spokeswoman for Regis and Kelly said that Starr had been informed of the time requirement for the song when he was booked last November.
