Guðbjörg Tómasdóttir, the Bubba in the Swedish/Icelandic group My Bubba, met My Larsdotter by chance eight years ago in Copenhagen.
Larsdotter says, "I had a room to rent in my apartment and I put up an ad and Bubba answered it. ... I was doing the dishes and singing and she came out and asked me to do the harmony on a song she was writing, and I agreed."
They've been singing together ever since — although it's not all perfect harmony.
"When we met, the whole thing went so smoothly," Tómasdóttir says. "I moved in the next day from when I saw the room and we just started singing together. ... We're also very much in sync with so many things ... the harmonizing [in our music] is a metaphor for that, I think."
And did Bill Clinton's nickname "Bubba" have anything to do with naming the group?
They both laughed, but no, the name comes from Tómasdóttir's great-grandmother.
