Before Susanne & Pernille were famous around the world as Me & My, they were already very young doing something with music and singing. In 1989/1990, they formed a singing duo called "SuPer Sisters". Notice that the 'P' is a capital, because the name is derived from their first names: SU(sanne) PER(nille). Good name choice from their parents I'd say :-).
They released two albums of danish songs, the first album being "SuPer Sisters" from 1989, and the second "Mariehoenen" in 1990. (Mariehoenen means ladybug :)).
They were even in the running for going to the Eurovision Song Contest in 1991, but they were kinda "disqualified" because the rules stated that no children could participate. They were too young.
Beware that the genre of these songs are somewhat different from Me & My, they are children pop songs. They were 13-15 years old, so that's normal :) They're all happy songs.
(Better scans of the first album will come...)
