In the b-side of Taiska's 1978 single was "Viistoista siis" (So, fifteen). The single wasn't any greater success, but this song was extraordinary, perhaps even unique, in the sense that it dealt with a woman's (seemingly sexual) attachment to an under-aged boy. We have often heard men singing about 'young girl, much too young girl', but a woman singing about 'young boy' is quite unusual, even today. In the song, the law-abiding woman apologetically tells the boy that he should be at least 15 years old before they can really do something. The original song was performed by Olivia Newton-John in her album 'Have You Never Been Mellow' in 1975 (released as a single, too). It was written by John Rostill and Bruce Welch from the Shadows. The storyline in this original version is quite different; the woman sitting in the bar begs that a cowboy would not play B-17 in the jukebox, becouse "it was our song, it was his song, but it's over".
