I understand your point, but in the instance of this song, I disagree. I'm ten years younger than Ted (he said he was 68 and I don't believe either woman's age was revealed), so Bobby Darin's version was hot a year before I was born, but that doesn't matter. It is such a HUGE classic song, that I have enjoyed every iteration of it since (look it up, there have been tons) and it is one of the songs I sing to my dog all the time (with different words). I would far rather dance to it than to "Can't Hurry Love" which is also a great song that has been done famously by some other people. "Beyond the Sea" is such a classic and the French version "Le Mer" is even more romantic. If I was dancing ballroom, I would love to dance to this song, which has lilt and beat and soft thrilling feelings and is super dancey. I also think that the woman who danced to it was thrilled with it.
Anna on the other hand. She looked uncomfortable with both men to me. Spectacularly uncomfortable with the first guy, somuchso that I hit the ff button. She was the first story that just didn't work for me on any level. I'm also glad to know that the show is going to be upfront about things not working out. I wonder if she wanted to meet the other guy after that, but I guess it would be hard to know you were the second choice.
