Finland returned to the contest in 1971 after skipping the 1970 edition (the only time we have willingly done so, btw, and also the only time the contest has not been broadcasted on radio/TV since 1959) with one of the hottest up and coming male singers, Markku Aro. He got backing from Koivisto sisters who also were quite popular show girls at the time but soon disappeared from the spot lights.
Markku Aro's debut single came out in 1968 and he scored big hits all 1970's. In the late 1070's - early 1980's he collaborated with Singapore born Nisa Soraya - until the romance lasted - and they were in Euroviisut 1981 with Mun suothan tulla vierees sun (5th) as well. He had also participated in Euroviisut 1969 (5th), 1974 (8th), 1976 (3rd) and 1979 (5th). But Markku's star was falling and he hasn't got a big hit since early 1980's even if he is still around recording and singing live and being quite popular and a household name. His latest album is from 2006.
