Booker T & The M.G.'s - Green Onions

Formed in 1962 in Memphis, Tennessee, Booker T and the MG’s (“MG” officially stood for “Memphis Group”, and is usually punctuated correctly on LP covers as “M.G”) became one of the most important soul outfits in the history of music. They were indispensable as the house band for Stax Records, backing many rising artists (Otis Redding, Sam & Dave, Albert King, and many others), but it was the MGs themselves that put Stax on the map with such singles as “Green Onions”, which reached number three on the Pop Charts, and “Hip Hug-Her”, which reached number six on the Pop Charts. 

The group consisted of four core members: Booker T. Joneson keyboards and organ (as well as many other instruments), Steve Cropper on guitar, Al Jackson Jr. on drums, and Donald “Duck” Dunn on bass. Cropper and Dunn were originally in the first house band for Stax, The Mar-Keys, and later were part of The Blues Brothers, both in the band and in the movie. Various others added horns and other instruments, and a young Isaac Hayes covered the keys on at least one session. Source: Last.fm
