I'm always going to remember "19 Growing Up" since it was used as a background song for a video that some of the members of the Japanese Canadian Students Association as it was known back then were making for Club Day. Although there wasn't any particular intention, Princess Princess' 4th single was inserted for some footage in which the then-president strutted into a volleyball court. Needless to say, he was pretty smitten when the triumphant intro blasted in just as he entered the court...or perhaps the Court. That was back in the early 90s.
"19 Growing Up - Ode To My Buddy" was released on the same day in February 1988 when Princess Princess' 3rd album, "Here We Are", came out. It was also the lead track for the album, and a pretty good one as well considering that intro and the title of the album itself. The song was written by Kyoko Tomita（富田京子）, the drummer of the group, and composed by lead vocal Kaori Okui（奥居香） as a celebration of that age for a couple of young women having the time of their lives.
Although I couldn't find out how far "19 Growing Up" did on Oricon, "Here We Are" peaked at No. 8 on the weeklies.
