In addition, in Britain, George Melly, Acker Bilk and Kenny Ball - though it depends how old the people are. Also Ray Charles, Nina Simone, Wynton Marsalis (probably), Diana Krall, Dinah Washington, Billie Holiday, Peggy Lee, Dave Brubeck, Glenn Miller, Benny Goodman, Bix, Harry Connick, Lou Rawls, Kenny G, James Brown, Quincy Jones, Nat "King" Cole - and others, too numerous to mention. I wouldn't expect large numbers of any population to know much about these people, including their music, but I'd expect recognition of their names.
