About Marty Grebb
Martin Joseph Grebb was an American keyboardist, guitarist, and saxophonist. A member of The Buckinghams in the late 1960s, Grebb was also a record producer and an arranger, who worked with musicians including Peter Cetera, Bill Payne, Bonnie Raitt, Eric Clapton, Etta James, and Leon Russell. However, Marty chose piano as his first instrument, turning to saxophone only two years later. Grebb received a writing credit along with bandmembers Peter Cetera and Kal David for the group's recorded song, "Come On Home". Grebb, Cetera and Dondelinger each went on to other groups that achieved greater recording success and national recognition.
