During the introduction, I often teach the progression with a "ring balance, walk past this neighbor", and I wanted something that included that. There are lots of great accessible dances with that (The Big Easy, Easy Peasy, etc), but I'm not seeing one with a partner promenade (something I also use in the introduction; to go from a big circle to lines of couples for a contra set).
If someone already wrote it, I'll happily give them credit. If not, I'll call it "If you can walk, then you can dance" (which I'll note is not an if and only if statement).
