- Rico: "Stabilizer" - Prod. by Keith Hudson; released on blank label 7", Jamaica; year unknown
- Gregory Isaacs: "Rock On" (12") - said an interview with DJ Ras Kush; but it's Vin Gordon playing here!
- Vin Gordon & The Upsetters: Musical Bone (LP: DIP /UK, ca. 1977), prod. by Lee Perry in Kingston /JA. De Koningh (2004, p. 123) gives credit to Rico & The Upsetters. This is definitely wrong; what we could not check is, if the UK release on DIP names "Rico and the Upsetters" as featured artists?! The material has been re-issued on CD (Justice League JLCD 5002)
