Accompanied by a large unidentified orchestra, Vaughan cuts loose on numbers such as "Be My Love," "Intermezzo," "Full Moon and Empty Arms" and "Ah Sweet Mystery of Life." Listeners who enjoy hearing her scat and swing are advised to look elsewhere but others who like when Sassy goes a bit over the top and really stretches her voice will find this unusual effort quite enthralling.
