Ben, good catch! So Ramsey now looks like the original.
Steve, the sole difference, beyond two or three points of punctuation and "Charmer's" spelling of "lain" for Ramsey's "ly'n," is that Ramsey (1740 and '50) places "Fall all de rall, &c." after each stanza while "Charmer" (1749) has it only once, at the end.
