Somg premiered in Australia last night...

But I didnt even think to write down the bands name or the song.
It was a song that was written for a friend at a wedding, (they said in the show)
She is wearing a bright red dress, the three other guys have weired looking insturments, along with being dressed from the 1800's?
There was an older man in the clip, he was pulling a boat on a rope, then tired to a tree by two men, where he is then there through rain snow and heat.
She had a very beautiful voice. Im sorry if I cant give anymore of a description. I've looked all over, and I just cant find it!
Thank you for your help!

What show, tv channel or ... ?

It was on Prime, Wollongong.
