John Gunnar Levén is the bassist in the Swedish hard rock band Europe. When he was 7 years old, him and his family moved to the suburb Upplands Väsby, where several members of Europe grew up. He joined the band in 1981, replacing Peter Olsson. In 1985 Levén was the one who suggested that vocalist Joey Tempest should write a song based on an old keyboard riff Tempest had composed years earlier. The result was the song "The Final Countdown".
