With a classical background behind her, McGregor moved very comfortably into the world of cabaret, incorporating both jazz classics and pop hits into her repertoire.
Along with her 3-piece ensemble, McGregor began the show with The Man I Love, Ain't Misbehavin' and Georgia, evoking the vocal styles of the great Billie Holiday and even Sarah Vaughan.
Terrific arrangements merged Justin Timberlake and the the traditional Cry Me a River, brought out a fine Sweet Dreams and created a superb jazz version of Britney Spears' Oops! I Did It Again, making it sound as if it was written to be performed this way.
Less successful was McGregor's encore homage to Prince.
Ali McGregor has a beautiful, rich, clear voice ideally suited to a style of jazz she clearly loves, and displays a fun sense of sexuality with numbers such as Whatever Lola Wants.
Her personality oozes warmth and she has a good sense of comic timing and story-telling.
