Jimsaku - Theme Of The Mint Club (1996) 

Downloaded from Tetsu Jino's channel a while back. Unfortunately, I don't have much more, and it's all on a failed HDD.
Nonetheless, this is the theme from Akira Jimbo & Tetsuo Sakurai (+friends)'s show The Mint Club. This may be familiar if you know Casiopea's The Mint Session DVD. This is the show it originally aired on in 1997. This theme however is early and was likely used very little, most episodes seemed to use a newer theme made in 1997.
