You might think that it's a tad early for a hammock-swaying song such as this one, but then again, "Kimi no Heart wa Marine Blue"(Your Heart is Marine Blue) [I think that's a compliment] was actually released in January 1984....nearly 30 years ago....pass the Geritol, dear. Kiyotaka Sugiyama（杉山清隆） and Omega Tribe took care of this one, right up in their wheelhouse of gentle beach-and-rolling surf pop. It's the melodic equivalent of an Orange Mimosa.
Omega Tribe's 3rd single was written by Chinfa Kan（康珍化）, a lyricist for a number of the band's songs and for hits by other artists such as Anri, Akina Nakamori and Mariko Takahashi, and composer Tetsuji Hayashi（林哲司）. It was the theme song for a TBS drama, "Toshigoro Kazoku"(年ごろ家族...A Family of Age), for which the band also appeared on apparently. Peaking at No. 12 on Oricon, it became the 45th-ranked song of the year, and was a successful seller in the stores with over half a million records sold.
