Tracklisting 1. Derrick Harriott - Keep On Dancing 2. Bobby Ellis & The Desmond Miles Seven - Now We Know (Instrumental) Taken from the epic 'Rock Steady Party' album, this Derrick Harriott's praise of the Rocksteady dancehall is for the first time ever released as a 7" single. The B-side, 'Now We Know', is an original single version of the song and is a great example of how good The Crystalites played the rhythms.
