All ears are different, but this doesn't sound like a Studio One recording to me, Dynamic perhaps. Delroy left Dodd acrimoniously, so IMO it reduces the liklihood of him re-recording a song he cut earlier for Dodd in the very same studio for another producer. Not impossible, just unlikely.
But regardless of whether it was or wasn't, quite a few producers cut records Studio One, as it was a working studio for rent. But I don't know if I would call these "Studio One obscurities", or else that label would belong to tracks like The Beltone's "No More Heartaches", and The Abyssinian's "Declaration Of Rights". Only a Studio One production could truly be called a "Studio One obscurity".
