I believe it's the correct tune for the dance! See and hear it here: abcnotation.com/tunePage?a=trillian.mit.edu/~jc/music/book/Thompson/Happy_Captive_THO4_108_The/0000 What a pity they are plodding through it rather than using a dance step. For me this tune cries out for a gentle 1-2-3-hop.

Sorry, that wasn't fair - they're not plodding, but they seem to be going through the motions rather than actually enjoying it.
