apparently they are 3 sisters from scotland who won a music competition...think they are young 17 or 18 ...not heard song on radio yet but have seen it on the music channel the Box, wicked vid and a bit trippy in places but still sweet, if ya know what i mean.
There's a yahoo group but I didn't find an official website. They are 3 girls - jennifer, kirsty and kendall from near Glasgow. The yahoo group seems quite up to date and the moderator may be able to answer more of your questions than I can. Hope that helps!
