U-Roy Version Galore Riddim Shower
Lord Koos (U-Roy) LORD KOOS
#KOO 25

  1. Call On I (V.Roy & D.Wilson)
  2. DJ Special (V.Roy & D.Wilson)

Featuring Delroy Wilson, the closest original vocal track I found is Call On Me on a Well Charge 7".
However, these U-Roy tracks use a slightly different riddim, more like You Keep On Running but with different lyrics.
Released on: 7" Dee Jay Foundation Skank I Am The Originator
