Exceptionally, there was a group of vocalists such as the early The Happenings Four, a guitarless GS, and the early Sharp Hawks, a chorus GS with a professional electric band in the background. In May 1965, while the popularity of British rock bands such as The Beatles spread to Japan, Shōchi Tanabe and The Spiders released "Furi Furi", which is considered to be the first Group Sounds record. In March 1966, Jackey Yoshikawa & His Blue Comets announced their first album "Blue Eyes".
