Kojo's first solo album, So Mean, was a hit in Finland. The second sold as well, though it was not considered quite as good. In 1981, his third solo album was a fiasco, so something new were to come. Enter to the Eurovision Song Contest!
In 1982 he represented his country with the entry Nuku pommiin (Ban the Bomb!) a rock song with music by Jim Pembroke and lyrics by Juice Leskinen ; the conductor was Ossi Runne . The song performed in Finnish was a protest against nuclear bombs and the danger of a nuclear war in Europe (The Cold War was still under way in 1982). Despite its pacifist message the song received no points (nul points). Despite this poor result, Kojo has continued his career in his native country.
Kojo's music has not been very popular in Finland after 1982. But every Finn remembers him due to his entry at ESC.
