I've seen the good chemistry between the male and female singers whenever they are paired up to sing duets - more specifically the older singers, the younger ones are usually very stiff - but "Sucho Monogatari" takes this chemistry to a whole new level! Never have I seen Kawanaka shake her behind or perform in such a comical manner before, but she did it so well that it allowed her to keep up with Yoshi's pace, and the product of that is a hilarious duet that tells the story of what goes on between the married couple when the husband has to leave for work/business trips.
So you have the usual stuff that all couples (I'm going to assume so) face when going through such a situation, like missing each other and counting down the days till the husband come back, the missus warning her man to not fool around when away, and the man being suspicious of his missus' friend. But the best part comes when the frisky fellow sheepishly and sneakily asks his companion if she wants a baby... out of other things, but his wife rebukes him, of course. Well... that's new. This set of humorous yet relatable lyrics can only come from the mind of none other than Yoshi himself. The Latin-themed music that Yoshi had composed also seemed rather strange at first, but that's the perfect score for some nutso dancing and prancing around.
"Sucho Monogatari" was released on 1st September 2000, I don't know how well it did on the charts as there wasn't a write-up on the song and the Oricon website didn't show its highest ranking either.
