Steely Dan co-founder Walter Becker sadly passed away this weekend, leaving behind an incredible legacy of masterful songs blending rock, pop, jazz and R&B. The guitarist and songwriter worked closely with Donald Fagen on Steely Dan songs, and wrote some of the band's most popular tunes, including the glorious "Peg" from 1977's Aja, an iconic album. Featuring Michael McDonald on back-up vocals and Jay Graydon on guitar, the song's airy melody and sweet lyrics make for a perfect love song. The tune was famously sampled by De La Soul in their delightful "Eye Know from 1989's 3 Feet High and Rising. Becker also released two solo albums and produced many records for others, including China Crisis and Rickie Lee Jones, leaving a deep and diverse legacy.
