S.O.S. (Pink Lady Song)

S.O.S. (Pink Lady Song)

"S.O.S." is a song Yū Aku and Shunichi Tokura wrote for Japanese idol duo Pink Lady. It was released as the group's second single in November 1976, and became their first number-one hit on the Japanese Oricon singles chart in the following year.

"S.O.S." features Morse code which stands for the song title at the opening of the song. Because its sound effect might be mistaken for genuine Morse code, intro of the track has been omitted occasionally when the song has played on the radio. The song has been one of favorites for both the duo and the fans, and it is also one of the essential songs performed in their concerts.
