There was a Public Broadcasting System presentation on some Swiss scientists who'd sent the digitized Mozart 40th through a system and, by their measurement, it arrived at its destination, quite undistorted by the trip, somewhat before it was transmitted. This was, of course, complicated by the fact that their time measurements were based on C being the ultimate speed, but, clearly there was at least one exception and that gave the perception of the event preceding its cause. It didn't seem that they made any assertions about what they'd observed. Perhaps they understand more than I about what had happened, but I didn't understand, and I doubt that they did, at least then.
