That's a tough line, you don't want to stalk the guy, but you want to stay on is radar. I'd definitely give it a few days. Then call him with a casual question, ask him something about the dance, like you remember a certain song and wanted to know if he knew the title of it. That way it's a friendly contact and a stress-free one. You want him to think of you as friendly and fun, not as a psycho stalker
