This is the guy I use to work for, I'd say he is fairly close to the founder of Jazz and R&B in the UK, When I worked at the record company (TKO/Ember Records) they had a catalogue of over 35,000 jazz and blues recordings... the roster looked like this
Jeffrey Kruger MBE
"Virtually every major name in the Jazz, R & B and Rock fields was to appear at the Flamingo - from Billie Holiday to Dizzy Gillespie and Erroll Garner to John Lee Hooker, Otis Redding, Wilson Pickett and Jimi Hendrix. Van Morrison's Them; Moody Blues; Deep Purple; Stevie Wonder and Status Quo all appeared at the club and it was the home base for Georgie Fame; Geno Washington; Zoot Money Big Roll Band featuring Andy Summers later of Police fame; and John Mayall's Bluesbreakers featuring Eric Clapton + Led Zeppelin; the Rolling Stones; the Who etc"
"Among the artists I have presented in concert through the years have been such wonderful and varied talent as The Jackson Bros; Gladys Knight and the Pips; Barry White; Marvin Gaye; Glen Campbell; Anne Murray; Tammy Wynette; Johnny Cash; Kris Kristofferson; Rudolph Nureyev; The Stars of the Bolshoi and Kirov Ballet companies performing 'Swan Lake'; Andy Williams; Dionne Warwick; George Burns; Jack Benny; Vic Damone; Al Martino; Placido Domingo; Jerry Lee Lewis; Bill Haley and his Comets and countless others. And this was called work!!!!!"
"This pioneering venture provided him with the opportunity to release music by some of the biggest names in R&B in the early 1960's, such as James Brown, John Lee Hooker, Jack Dupree, B.B. King, the Platters and Billy Ward's Dominoes, featuring Clyde McPhatter and Jackie Wilson"
