The music on The Swingin's Mutual!, a dozen selections featuring the George Shearing Quintet includes six that have vocals by a young Nancy Wilson, and has been reissued on CD by Capitol with five additional tracks. This was one of Wilson's most jazz-oriented dates (even if she was never a jazz singer) and is highlighted by her vocals on "The Nearness of You" and "The Things We Did Last Summer" along with instrumental versions of "Oh! Look at Me Now," "Blue Lou" and "Lullaby of Birdland."
