Favorite J-pop Singles: B'rouge / Growin' Glory

This is a single by a group that I know almost NOTHING about! In fact, the ONLY information I have on this pretty vocal duo is the info that is on the 3" single sleeve! So here goes: B'Rouge is a duo consisting of two vocallist: Ritsuko Kurosawa and Michelle A. Key. Oh, it also states that it is  the Campaign Song for "Mizun(?)" Mizun? Am reading that right?
OK, so how did I ever come across this obscure song? Well, years ago, someone at my workplace threw this song on a j-pop mix cassette tape for me, I think HE got it off a sampler they circulate to the j-pop buyers. I seem to recall "Itsumademo" by Chisato Moritaka was on that same sampler! After a few listens to that cassette, I had the single special ordered for me thru Tower Records, cause I knew I had to have a "hard" copy!
Anyway, It is a TOTALLY infectious catchy little tune, featuring some terrific voices, slightly reminiscent of Kohmi Hirose (for you Kohmi fans like me!)...check it out!
