Formation: Circle; Couples Facing Anti-Clockwise
Music: Own tune and words. Some of the actions relate to the words.
If you search for "I've been to Harlem" or "Turn the Glasses Over" you will find videos of people dancing this. The common features are:
Promenade.
At "turn the glasses over" some people twirl.
Men circle in one direction; ladies in the other.
Grab a new partner.
The footwork in the version below is more complex than any other version that I have seen.
Where you have been to in the song varies depending on who is singing it. There are lots of examples of Haarlem, rather than Harlem, which seems more likely as the original words since Haarlem is a port in the Netherlands and Dover is a port in England.
