Sir Duke is a song by Stevie Wonder from his 1976 album Songs in the Key of Life. It was released as a single on March 22, 1977, with He's Misstra Know-It-All as the B-side. The track is a tribute to Duke Ellington, the jazz legend who died in 1974, and it also references Count Basie, Glenn Miller, Louis Armstrong, and Ella Fitzgerald in its lyrics. Blending funk, R&B, jazz and soul, the song runs about 3 minutes and 53 seconds and features Wonder on vocals and electric piano with a horn section. It topped the US Billboard Hot 100 and the R&B chart, peaked at number two in the UK, and was re-recorded for the 1995 live album Natural Wonder.
