My BFF had this skill: whenever they sang an Elvis tune (like “Blue Moon”) their cats would start humping. They weren’t singing it weird, maybe a little more warbly than normal. Anyway, we were in this zoo once, and I said, “I wonder if that lion would react to your Elvis songs the same way your cats do!” I was just kidding, but my BFF started singing the same way and that lion suddenly became VERY alert and stared right at us. I started wondering if a properly motivated lion could leap that gap that was keeping us separated, and what I would do if it reached us. Anyway, my point is: it depends on how you sing it.
