James played this at a session and I thought it was pretty tune and not too hard (although easier on a box than a fiddle!). It is written by Phillippe Prieur and although a waltz, apparently French waltzes are faster than English ones. The name translates as Your Pretty White Skates.

Some good recordings on Youtube (not sure of key):
Tin whistle
Accordion
French pipes
Melodeon (but played in G)
