Background-
Group of friends, all couples, friends for about 4/5 years. DH and I got married last year and this particular couple came. Earlier this year, all couples together watching films and the song that came on when the credits rolled so DH and I decided to recreate our dance after a few drinks. A few days later female friend said to me that that was actually the wedding song they have planned, they had completely forgotten we had used it at our wedding (how could they?! Our dancing was amazing, lol) and did I mind? Of course I said no, it's a song, who has ownership of a song etc.
Fast forward to their wedding this weekend, and they used said song, but also had exactly the same dance routine. I mean, everything identical (we went to lessons and learnt it). Isn't that a bit weird? Like less than 12months later they're doing the same dance routine to the same song? Even if they went to lessons to learn it (but they say they haven't had lessons) then they could ask for a different routine ?
I know you can't have ownership of a song (or a dance) but AIBU to expect that you at least do your own version? Mutual friends attending both weddings so if they care (probably don't) it would be pretty obvious.
