Researching this was confusing, because Scientist and Greensleeves had a copywrite dispute in 2005. The Scientist backed album is called Scientist & The Space Invaders, and this song is called “The Red Planet”.
The original was released in 1981, on Scientist Meets The Space Invaders, which is one of the all time classic dub albums.
The basis for this dub version is “I’m A Dreadlocks” by Sammy Dread and Papa Tullo from 1980, on the Strong Like Sampson label.
It’s masterfully done, playing off stop-start drums and a punchy bassline while a swampy yet refined guitar picks out an intermittent tune overhead.
Truly, everything Scientist touches turns to gold!
