Sirkka Keiski had a short career as a pop singer in the latter part of the 60's. She recorded only three singles as a solo artist and two more as a member of female vocal trio Kolmiapila. In 1969 the pop music press labeled Sirkka as 'Miss Soul'. And from the same year is this recording "Mä heräsin" (I woke up). On this record Sirkka is backed by the group Soulset, one of the rare Finnish soul groups of the era. The arrangements were done by group member Seppo Paakkunainen. On the B-side of the single was another Supremes cover "Ei vieläkään" (Baby Love). So, the original song was performed by The Supremes and it was called "The Happening". The song was the theme song of the 1967 comedy film "The Happening". The film was only a minor success, and is most notable today both as one of Faye Dunaway's earliest films and for this theme song. "The Happening" became a number 1 hit on the Billboard Hot 100. You can see Supremes perform the song, here.
