Doing research on Vee-Jay Records for a Dells feature I'm to write I came across this indepth website.

Vee-Jay were a great label, the first really successful African American owned label, who had hits with The Spaniels, Jimmy Reed, Jerry Butler, John Lee Hooker, The Dells, Four Seasons, lots of gospel and jazz and even The Beatles initial US releases! Oddly underrated label considering their legacy.
