I am sure it is the same, as the words I learned at the women's groups was "sister" etc. I have sung it starting with "friends", then on to "brothers", then "sisters".Libana has a song book out with their acapella arrangement, too. Here's a a clickie for their website with lots of info. Mudcattrer Animaterra's groups sings a lot of the types of songs they do, too.
Thanks!
