Sai laulu aikaan sen" (It was caused by a song) in 1977 to the lyrics of Pertsa Reponen. It was released on their debut album and also as a single, but was lost in oblivion. The song was considered to have some hit potential, becouse two other Finnish versions were released in that year. The original song was called "Ensename a cantar" (Teach me to sing). It was the Spanish entry in the Eurovision Song Contest 1977, performed by a singer named Micky. The song is an up-tempo number in which the banjo plays an important part. At the close of voting, it had received 52 points, placing 9th in a field of 18. You can see the actual ESC performance, here.
