We Did It Too Well and You Could Hardly Tell
Didn't watch the vid. Maybe later when we're in town on the non-data-capped cable connection.
Meanwhile, good morning. (Still is here, anyway.)
Many decades ago, elder brother and I recorded a song, flipped the tape (reel-to-reel, those were the days), and learned to sing it backward, recorded that and flipped it back. Alas, we did it too well and you could hardly tell it was backwards-backwards.
Just thought you needed to know that.
