Here we have some very good hi-life from Ghana from the mid 80s. Jewel Ackah is well known enough to have stuff you can by on Itunes but not this album. I found this vinyl album in the Princess May car boot in Dalston, which is almost the equivalent of the Dalston Oxfam Shop (for me) these days because they don't really care any good tapes anymore.
It looks Jewel Ackah had albums dating back to '81 as you can see from his discogs site. You can see some more recent albums of his (less to my taste) on itunes here.
According to his biography here, this is maybe his best album, recorded with Pat Thomas and A.B. Crentsil.
