The Swingin's Mutual! is an album by the George Shearing quintet, accompanied on seven songs by the vocalist Nancy Wilson. The initial Billboard review from March 13, 1961 commented of Wilson's singing that "These are standout renditions by the youthful thrush, in which she offers fanciful, stylised and sometimes moody interpretations as "Born to Be Blue", "The Things We Did Last Summer", "Let's Live Again" and "On Green Dolphin Street".
