Strøm's final Eurovision appearance, at the 1976 contest in The Hague on 3 April, ended in complete failure, as "Mata Hari" placed last of the 18 participating songs. Prior to the contest "Mata Hari", a very modern and contemporary disco-style song, had been expected to do well, but it was suggested afterwards that Strøm's rather odd outfit and performance on the night may have cost votes. With two last-place finishes from three entries, Strøm is usually cited as the least successful artist to have appeared in more than one Eurovision Song Contest as the only artist to date finish in last place twice.
