There's my thumb (My sweetest May, let love incline thee)

The original words to the old Scottish song "There's my thumb" appear to be lost; these lyrics were first published in the Tea-Table Miscellany in 1724. Another set of lyrics, believed to also be Ramsay's, can be seen at There's my thumb (Betty, early gone a Maying).
