I recently acquired an excellent Derrick Harriott reissue on Doctor Bird (Cherry Red's reggae reissues brand). It comprises two albums from 1975 - "Greatest Reggae Hits" and "Reggae Disco Rockers" - and lots of versions and other bonus tracks.
Here are a couple of tracks from "Greatest Reggae Hits". The first is an original and the second a Billy Paul cover. The album, and a compilation as a whole, is an entertaining mix of originals, versions, cover versions and versions of cover versions.
On "Reggae Disco Rockers" Derrick gives us his take on the two songs in the videos, proving yet again that there isn't any song from the 1970s that doesn't have a Mandatory Reggae Version.
"Face Dog" - Derrick Harriott
"Brown Baby" - Derrick Harriott
