Eric Clapton wrote the music for the one and only Derek and the Dominos album while still completely obsessed with Pattie Boyd. "Bell Bottom Blues" was the first song he finished for the project. "Pattie asked me to get her some pairs of these jeans we used to call Landlubbers," Clapton wrote in his memoir. "Which were hipsters with two little slip pockets at the front. She had asked for flared rather than straight bottoms." That simple request led to one of the all-time great unrequited love songs in rock history, and Clapton's anguish is painfully clear in every note of this song.
