Couple of tasty Hugh Masekela edits, both off his 1984 album Techno Bush. The first is from Australian DJ Hober Mallow (Lachlan Holland).
The second edit is a great tune which got reissued on vinyl a few years back - I'm told it was popular in Auckland clubland back in the day on first release. The original 12-inch also had a great dub mix on it, which you may be able to find floating round the internets. This edit is from Serbian production duo Kompleks.
