"Though I don't hear any skip in the recording, I believe that a couple of lines have somehow been dropped after the "punt" line. There should possibly be a couple of lines to set up the rhyme on "trick" - instead of what might have been expected."

I think this is the case, too.

"Salter seems to sing "wrinkle" (not "ring a") but I can't make any sense of it."

It sounds to me like "every time I think of/on thee"....though I realize that might sound too fancy.
