I've had a melody (and its lyrics) stuck in my head for decades now from a song I heard in the 90s. It was a line in a dancehall song, but I just can't remember what that song or the artist was. So recently I actually tried in earnest to find that 90s song. I still have not found it, but in doing so, I realised that the melody is actually quoting another much older song (I should have known).
And now, I've found a bunch of versions of that original song (it must be popular, I just did not know about it!). I see versions by Dennis Brown, The Skatalites, Anthony B and the Mighty Vikings. But I'll put the version here from Johnny Clarke cause I'm diggin that vibe today...I'm still on the hunt for my song, but the internet/youtube can be a wonderful thing.
