With the help of pianist-arranger Paul Shaffer, Belushi and Aykroyd started assembling a collection of studio talents to form their own band. These included "SNL" band members saxophonist "Blue" Lou Marini and trombonist-saxophonist Tom Malone, who had previously played in Blood, Sweat & Tears. At Shaffer's suggestion guitarist Steve Cropper and bassist Donald "Duck" Dunn, the powerhouse combo from Booker T and the M.G.'s and subsequently almost every hit out of Memphis' Stax Records during the 1960s, were signed as well.
