From the wiki: “‘Don’t Let Go’ was written by Jesse Stone, and was first a hit for Roy Hamilton (‘Unchained Melody‘) in 1958 before covers by Mel Tillis, Commander Cody, and Isaac Hayes charted in the 1970s. One of the more interesting of many cover recordings done of ‘Don’t Let Go’ was produced by The Four Seasons in 1964; very much against their archetypical sound. The 1965 cover by The Graham Bond Organization (including bassist Jack Bruce and drummer Ginger Baker) was one of the first Rock tracks to feature the Mellotron.
“Stone was the leader of a Jazz band during the 1920s that included Coleman Hawkins. In 1936, with the assistance of Duke Ellington, Stone was booked to perform at New York City’s famed Cotton Club, and would later become a staff arranger/writer at the Apollo Theater. He would go on to join Atlantic Records as songwriter and producer, where he wrote ‘Shake, Rattle & Roll‘ under the pseudonym ‘Charles Calhoun’, first recorded by ‘Big’ Joe Turner.”
