The DT has "low" (Child #100) - can anyone check Child to see whether the DT entry is correct? And, since Janet is naked, she isn't wearing an apron high or low...??

Which song in the DT are you looking at? There are 3 songs that I found in the DT that (Careless Love, I Wish I Wish 4 (Died in Vain), and Dink's Song) use the conceit of when I wore my apron low, he liked me, and now that i wear it high, he doesn't. None of the 3 mention Child 100.

In my Loomis Press edition of Child, Willie O Winsbury (100) has J permutations (counts on fingers ... that's 10). There's none of them has anything about aprons.
