Following the success of The Blues Brothers on SNL, Belushi and Aykroyd, with the help of pianist-arranger Paul Shaffer, started assembling studio talents to form a proper band. These included SNL 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's Stax Records during the 1960s, were signed as well. In 1978 The Blues Brothers released their debut album, Briefcase Full of Blues, with Atlantic Records. The album reached #1 on the Billboard 200 and went double platinum. Two singles were released, "Rubber Biscuit", which reached number 37 on the Billboard Hot 100 and "Soul Man", which reached number 14.
