The first TeamGym Contest took place on what date ?
" Lykken er " marked Norway 's return to Eurovision after their first of only two absences to date since their debut , when they were one of five nations to boycott the 1970 contest in protest at the four - way tie in 1969 and the fact that they ( along with Finland and Sweden ) considered that the voting system of the late 1960s tended to place the Nordic countries at a disadvantage .
