Bee-dubya, your ref. to "that stiff cadence that they're usually done in and just pretend you're playing them for a contra-dance: Deck the Halls" took me aback! Deck the Halls (Nos Galan) is a dance tune and, even when we sing it here, it still goes like the clappers. The dance version has a few more twiddly bits in it than the sung one, and is a VERY popular dance tune in twmpathau (folk dances)! I could probably scan the dots for it (and the other two usually included in the same set) if you PMed me.

p.s. Is 'going like the clappers' trans-atlantic or a Brit thing? Or maybe Welsh? I've lived here so long I'm not sure what's understood where!
