Independent label Reggae label and publishing concern, founded by Byron Lye-Look. Congo issued just the one single in the 1970s, 'Nation Fiddler', by Macca Bees (CO-1), which came out in 1977.  For some reason its second single, Jah Lion's, 'Melody for Negus' (COS-2), didn't appear until 1983.  That record had a differently coloured label - light blue instead of red - and a slightly altered prefix. Thanks to Robert Lyons For The Info.
