I liked the video, so I uploaded it to my channel, I don't think it's wrong.
The video itself has the credit in the beginning and ending.
I'm not sure if somebody else did that and wasn't supposed to be there but that's how I got it from youtube.
FYI, youtube has several copies of videos uploaded by uploaders., that's what Youtube is all about.
If this swedish family want me to take the video down, I'll happily do that. But I just uploaded it to my channel, because I wanted
to keep it on my account and be not worried about the poster taking their videos down.
And, hillguy, thanks for posting more of these videos. I'll find the original poster and update description on my video very soon.
