Well, Tradsinger, I mentioned the convention in my notes to my Brewhouse record Butter & Cheese & All (BH8904); where I wrote, re The Tailor in the Teachest, "Conflict between sailors and tailors (cf I'll go and List for a Sailor) seems to be a result of more than just the fortuitous jingle of the names; perhaps they are supposed to represent two extremes of manliness?"

I do not flatter myself that this is necessarily (or even probably!) the reference you are seeking; but wherever you may have read it, it was surely rehearsing something of a folk commonplace?
