According to a "Sound on Sound" magazine interview with Neil Dorfsman, the performance of then-permanent drummer Terry Williams was considered to be unsuitable for the desired sound of the album during the first month of the recording sessions. Williams was temporarily replaced by jazz session drummer Omar Hakim, who re-recorded the album's drum parts during a two-day stay before leaving for other commitments. Both Hakim and Williams are credited on the album, although Williams' only contribution was the improvised crescendo at the beginning of "Money for Nothing" and "Walk of Life".
