It sounded exactly like Louie Malongo, but I couldn't hear it properly over the professor. Definitely modern South African. Happy, jangly guitars and catchy chorus, sort of a Johnny Clegg feel. It sounded like "Afrikaana" was one of the lyrics, and title was possibly something along the lines of "Rhoomba all the way".

Chorus seemed to be all male, it had a sax solo. Another possibility I've tracked down is Louis Maholo, but he's just a drummer and I can't find any of his albums or tracks.
