For Katja Nord and Camilla Dahlin, a good tribute band is all about the details. Down to even the lengths of their manicures, the two singers are focused on being as true to character as possible.Nord and Dahlin fell in love with ABBA when they were 9 years old after the group won the annual international song competition Eurovision. Immediately, the two young girls were hooked and from then on, the members of ABBA were idols in their eyes.
