BED, Bedlam (Blue Swing). BED is the acronym for vocalist Becky Kilgore, guitarist Eddie Erickson and trombonist Dan Barrett. The group also includes bassist Joel Forbes, but the name BEDJ wouldn’t make much sense. What does make sense is Ms. Kilgore’s sunny, flawlessly in-tune singing and the way she interacts with the easy-going playing and occasional singing of her three co-conspirators in the art of delivering fine songs. BED’s repertoire includes great standards and some unusual entries: a banjo medley of tunes from “Oklahoma,” for instance. And when is the last time you heard “My Canary Has Circles Under His Eyes?”
