SLM if you like 80's music you may like the British Beat - although it's far from techno. This band got many of my crew dancing for the first time back then. The music is ska with a slightly punk element, but it's hard not to move your feet, especially when the first album comes complete with a pic of Beat Girl and simple feet moving instructions
Oh, and having a serious foot fetish, I know lots of things involving feet and sex
If the record don't do it, try first dancing on the bed. For over 5 years we had a party room known as the paradise garage (its now my work area). We had a large steel framed bed in it and have many photos of people dancing on that bed. Needless to say, other things often followed ... :D
