Jimmy Nolen - born 3rd April, 1934 (Oklahoma City) [died 18th December, 1983]
He had half a dozen singles issued by King/Federal Records during 1955/7, including 'After Hours' (named by Roy Buchanan as his favourite record - he said Nolen was the first person he saw bending guitar strings). 'The Way You Do' (1956) should appeal to admirers of James Hunter http://www.youtube.com/watch?v=e3044iCMQuE
He replaced Pete "Guitar" Lewis in the Johnny Otis Show in 1957, famously playing on 'Willie and the Hand Jive' and (I think) 'Castin' My Spell' (1959 - vocal by Johnny & Marci Lee) http://www.youtube.com/watch?v=Ch6rCaibNe8
He had his own band in the early 60s, mainly backing other artists including George "Harmonica" Smith. Joined James Brown in 1965 - his first session was 'Papa's Got a Brand New Bag' - James' first UK hit. Formed a partnership with the other guitarist Alphonso "Country" Kellum (who joined James the same year) until 1970 when the entire band quit. 'Give It Up or Turnit a Loose' (1969) http://www.youtube.com/watch?v=G1_ctj5jx_s
Jimmy rejoined the JB's in 1972 and remained for the rest of his life.
In 1984 Lee Hildebrand interviewed Nolen at length which was published that year by Guitar Player under the title of A Rare Interview with James Brown’s Longtime Sideman - the Father of Funk Guitar. I think it was reprinted by them a couple of times, once as a truncated form of obituary.
