American retired songwriter, record producer, and musician, known for joining and naming Blood, Sweat & Tears, although he did not stay with the group long enough to share its popularity. Throughout much of the 1960s and 1970s he was a prolific studio musician, including playing organ on the Bob Dylan song "Like a Rolling Stone", French horn and piano on the Rolling Stones song "You Can't Always Get What You Want", and lead guitar on Rita Coolidge's "The Lady's Not for Sale". Kooper produced a number of one-off collaboration albums, such as the Super Session album that saw him work separately with guitarists Mike Bloomfield and Stephen Stills..
