Hi! I watched the video closely and I did catch the mistake. At 1:40 in the video, the leftmost Beatrice disappears for a few frames. It's a very quick mistake, but it's definitely there.
I also enjoyed the video. Beatrice has a beautiful voice and she's a lot of fun to watch. I'm glad you shared it with me!
I hope you had a great night time walk. The full moon is always a treat.
I looked for lefty leaving but didn't notice it, but it's been a long day and my eyes are tired, I'll check it again soon.
Yeah, she has a great voice, I like her covers. :)
