Listed where? Strip the Willow is a dance, not a tune; it's usually danced to Drops of Brandy or other 9/8 jig. I can't say that it bears much resemblance to Pop Goes the Weasel. Bab at the Bowster appears in a number of forms; vaguely similar, but not especially so. The set in Gow is yet another variant, a 6/8 jig called The Cushion Dance from the dance with which it was associated at the time. Also not particularly reminiscent of Pop to my ear. A set of The Hay Makers also appears in Gow (also a 6/8 jig of similar shape), but there are others.
