John Robert "Joe" Cocker OBE 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.
