42. "Monday Morning"
When Buckingham and Nicks' 1973 debut album proved a commercial failure, Polydor dropped the duo. But Buckingham had already written a handful of songs for a follow-up. "[They] were showstoppers, even as rough sketches recorded on Lindsey's four-track," Fleetwood raved years later. Among these was "Monday Morning," and after being fleshed out in the studio, it became the lead track on Fleetwood Mac. When John McVie wondered if the band's new material had wandered too far away from the blues, producer Keith Olsen responded, "We're doing pop rock now. It's a much faster way to the bank."
