Walkin Appears on “The Complete Live at the Plugged Nickel 1965” (Columbia Legacy 1995). It is originally written by R. Carpenter.
Played live at the Plugged Nickel, First Set December 23, 1965 by:
Miles Davis – Trumpet / Wayne Shorter – Tenor Saxophone / Herbie Hancock – Piano / Ron Carter – Bass / Tony Williams – Drums.
Research for a Wayne Shorter biography revealed that drummer Tony Williams, during the plane ride to Chicago, challenged the rest of the band to play anti-jazz, in essence sabotaging the gig by playing whatever one wished rather than the standard versions. The band kept to the challenge, and the tunes were then radically altered for the Plugged Nickel performances. [source]
