It's a T&T LP, obviously trying to cash in. Joey Lewis and Frankie Francis were both bandleaders and arrangers who worked with the big calypsonians in the 60s and 70s.
Your review seemed detached from the Wailers history. As your examples of what ifs of rock musicians show, your perspective is not of the Wailers as Jamaican musicians. Jamaican music did not work like the US/UK music industry.
And staying in Jamaica was not going to change the fact that Bob's ability as a songwriter was pulling him away from the other Wailers. This LP just accelerated the changes already happening in the partnership that was the Wailers.
