[Callers] Dances licensed with CC or similar

Hi all: Does anyone here know of any dances that are licensed under an open (free as in freedom) license or have fallen into the public domain (it's hard to find dates for a lot of older dances)? I'm already using a few of Seth Tepfer's dances which are licensed under a Creative Commons (CC BY-NC 3.0) license [1] (Thanks Seth; I owe you a beer or something!) and wondered if anyone else had licensed their dances in a similar fashion? I know that most callers don't mind if people include their dances in non-commercial teaching materials or call them at dances (implicit CC licensing is sort of ingrained in the culture), but I'd like to stick with things that are verifiably in the public domain or have explicitly been released under a CC or similar license. These would be used as example dances in the typesetting project that I mentioned recently (which will hopefully be published sometime next week). Thanks, Sam P.S. I always wonder why more callers don't do this; lack of knowledge that such things exist? P.P.S. As a matter of public record: All of my dances are _always_ released under CC BY-NC 3.0 license unless otherwise marked or stated. I also waive the noncommercial restriction for the purpose of calling them at a dance.
