I've heard about canoe ballet, where the paddler dances the canoe over still water. John has some interesting video, and there's some writing online done by Becky Mason about her Classic Solo artistic canoe paddling. We've even written a little about dancing here on Kayak Yak... not much like what Becky Mason does, alas.
But there's some actual dancing being done in actual canoes by dancers and paddlers. Check out this video choreographed by Tanya Williams. It's called "Riverbank Fandango" -- presented by the Wellington Water Watchers and the Two Rivers Festival in Guelph, Ontario, on June 15, 2012.
If you don't see the video here, you can look on Tanya's own website, or see it at the website of one of her colleagues, Sarah Tolmie.
