Many of the early quadrilles expanded into cotillions that were danced by the entire room in a circle. Just as 8-some expanded into 16-some (horrible dance), 32-some (lots of fun, and fond memories with Bill Ireland at the dems the summer school used to do at Pitlochery. Then of course there is the book <<The General Danced at Dawn>> that has a 128-some (mind boggling).
Regarding my previous post, I just thought of another way of dating the book edited by Diack. In looking at his his items, there is only one that seems a bet contemporary as compared to the others. This is, as you mentioned, "The Barren Rocks of Aden". I first became aware of this tune at ceilidh dancing as one of those for the "Gay Gordons". I think the connection with the Gordon Highlanders, is that it was written to commemorate their posting in what is now Yemen, on the Gulf of Aden. So if anyone knew the time of their stay there, or the date of that tune we would then have a date, after which this book would have to have been published. Because of the price and dances, I would say before 1930, at which time Diack was editing Society publications, and the country dance tunes he includes were all published by the Society before that time.
