After the high standards established by "Band on the Run" and "Venus and Mars," Paul McCartney and Wings display their group unity by producing a remarkably mediocre album. Released to coincide with the band's American tour, "Wings at the Speed of Sound" (1976) has two hit singles - "Silly Love Songs" and "Let 'Em In" - the snappy rocker "Beware My Love" and plenty of obvious filler. The low point is Linda's embarrassing "Cook of the House." Despite the tour's phenomenal success, the decline of Wings as a studio entity begins here.
