is the 16th single of duo Pink Lady, released on December 5, 1979. The song was originally chosen to be the theme song for the Japanese teams at the 1980 Summer Olympics in Moscow, but Japan became one of 66 countries to boycott the games following the Soviet invasion of Afghanistan, thus affecting the song's sales.[1] [2] This was the duo's first single not to reach the top 20 in Japan.
The song sold 300,000 copies.[3]
A re-recorded version of the song was included on the 2-disc greatest hits release, INNOVATION, released in December 2010.
