There was no 12" - LP track only, although, sshhh, Shaka did run it on dub plate at the time. Imo, there's some other good tracks on the LP, "Where Is Jah" - recut of The Regulars tune - Kingpin was their singer at one time - "Sheba's Verandah", "Daughter Of Israel", the rest of the tracks though veer a bit too much towards lovers territory for my liking. Non of them sound remotely like "Little Jimmy" either - that track definitely stands out! Also worth checking, if you can find it, is an earlier Ariwa 10" of his called "Little Black Bombo".
"Little Jimmy" is from 1990, btw!
