"Green Onions" is an instrumental R&B hit recorded in 1962 by Booker T. & the M.G.'s, "one of the most popular instrumental rock and soul songs ever." The tune is twelve-bar blues with a rippling Hammond M3 organ line. The guitarist Steve Cropper used a Fender Telecaster on "Green Onions" as he did on all of The M.G.'s instrumentals.
