Barry, I assume that 'shoe' in that last excerpted lyric means 'shore', right?

Also, this is somewhat off topic, but as I'm sure your knowthe West Indian tradition of insulting songs comes from an African tradition. For instance, the traditional musicians/singers/storytellers/historians of Senegal & The Gambia-called jalis or [the French term] griots sang either praise songs about one's ancestors or dissing {insult} songs. It depends on who their sponsors were and what they "paid" to do.

Btw, another African tradition carryover is the tradition of praising oneself in songs. You can hear this tradition in examples of songs from Blues, Calypso, Hip-Hop, and other African Diasporic [if that's a word] genres. You can also see it in the royalty and status tag names that artists from those genres give [or, in the case of blues, used to give] themselves.

Why Blues artists stopped giving themselves tag names is a whole nuther line of inquiry, but I think it would be an interesting one that also might address why many Black people aren't "feelin'" the blues.
