The Grease Band was a British rock band that originally formed as Joe Cocker's backing group. They appeared with Cocker during the 1960s, including his performance at the Woodstock Festival in August 1969. The band's name derived from an interview Cocker had read with the American jazz organist Jimmy Smith, who had approvingly described another performer as having "a lot of grease", with "grease" referring to soul. After Cocker formed the Mad Dogs & Englishmen album band line-up, the group released two albums without him in the 1970s.

John Robert "Joe" Cocker was an English singer known for his gritty, bluesy voice and dynamic stage performances that featured expressive body movements. Most of his best known singles, such as "Feelin' Alright?" and "Unchain My Heart", were recordings of songs written by other song writers, though he composed a number of songs for most of his albums as well, often in conjunction with songwriting partner Chris Stainton.
