Christine McVie's single most cherished track from her own recordings was not created with Fleetwood Mac at all, but appeared on her overlooked 1970 solo debut, released under her maiden name, Christine Perfect. She later dismissed the record to Mojo magazine as "a half-hearted project", admitting she "didn't feel confident in a solo world" at the time, yet the album arrived while she was already easing into a permanent role in Fleetwood Mac following Peter Green's departure, ahead of her formal induction into the band on 1971's Future Games.

The song in question is the album's opener, "Crazy 'Bout You Baby", a cover of a 1950s Sonny Boy Williamson tune that Ike & Tina Turner had also recorded as a 1969 B-side to "The Hunter". McVie praised her own stripped-back version decades later, recalling the "little Hohner transistor piano, under-produced" sound and calling it her favourite track on the record. The article also notes the wider context of her career, from her earlier hit "I'd Rather Go Blind" with Chicken Shack to her later chart-topping success as a Fleetwood Mac songwriter on hits such as "Everywhere" and "Little Lies".
