Rosemary Clooney may be an old-fashioned singer vis-a-vis the fast-track that jazz and pop vocals have been on for a decade or so, but her down-to-earty swing and her melodic approach to song has not become dated. Nor has the elegant 1940s saxophonic voice of the young tenorist Scott Hamilton, who shares the bandstand with Clooney at Charley's through Sunday.

Dividing the set about equally between slow-ballads and driving up-tempo numbers, Clooney was at east with both. On a Cole Porter medley she wedded the words closely to the intricate piano lines of John Propst on "Get Out of Town," displaying a good feel for the subtle inner rhythms of the song. In contrast, her delivery of "'My Heart Belongs to Daddy" was boisterous and stomping. The Billy Holliday vehicle "Everything Happens to Me" and several other ballads were invested with convincing passion.

This is a singer who doesnt" blow horn lines and doesn't drop the words in favor of percussive scat. She just swings sophisticated lyrics around classic melodies and does it with the kind of class that is not much in evidence these days. She was given fine support by her quartet, which included, besides Hamilton and Propst, bassist Steve Novosel and drummer Jerry White.
