Sorcha, most of the polkas I found were in cut time, and I didn't find any in 3/4 waltz time. Still, there's something about a polka that feels like a waltz. Can somebody define just what a polka is?
This thread was a general request for polkas. I think I'll add one of my favorites. I found it on a "Paul McCartney & Wings" site, so I imagine McCartney did it.

Well just because you think I'd be lonesome
And just because you think that I'll be blue

I'm through with you

Hmm mm because, well well, just because
