North West London Reggae Band?

[luther brown]

I'm trying to obtain a recording from the 70's or 80's of a London reggae band originating from the South Kilburn area. As far as I know they only had one well known hit which I'm sure would be easily recognisable to even the most casual of reggae fans but unfortunately I can't remember the name of the song or the group. I thought they were called "Natural Mystic" but a search on the Roots Archives hasn't come up with anything. They're from the South Kilburn area and as far as I know there weren't that many bands from this part of London so I thuoght I'd try the message board to see if people could give me names of a few bands that I could look into. Any ideas?Thanks.
