Elvis Costello's long-delayed covers collection _Kojak Variety_ (Warner Bros, four stars) - recorded in 1990 and widely bootlegged since (note from me: gosh, who would do such a thing? Not a real fan, certainly...) - not only avoids most of the pitfalls inherent in such projects, but also manages to add a meaningful chapter to the artist's ouevre. The quirkily personalized song selections - 15 non-hits borrowed from the likes of Williw Dixon, James Carr, Randy Newman, the Supremes and Screamin' Jay Hawkins, including a previously released reading of Ray Davies' "Days" - drives Costello and his stellar sidemen to consistently smart and soulful interpretations, but the fact that _Kojak Variety_ is far superior to Costello's 1981 country-standards misfire _Almost Blue_ has less to do with stylistic variety than with Costello's maturation into a generous and expressive performer. Then it adds, same paragraph: On the other hand, Duran Duran's long-in-the-works tribute to their forefathers, _Thank You_ (Capitol, one star) is well-intentioned and makes some interesting choices - including a Costello tune - but sucks anyway.
