Also, a little more about the new singles.
The first single, TWL/Yellow Pansy Street, will be released on Wednesday April 20.
TWL contains two new songs. The first, TWL, is the current opening theme for Crayon Shin-chan. Yellow Pansy Street will be the theme for the Crayon Shin-chan movie (which Ohkura and Murakami have guest roles). The title of the single actually changes depending on which version you buy (the anime version lists TWL first, while the movie version lists Yellow Pansy Street first).
The limited edition for the anime version has a 「T.W.L」 Music Clip and Making video.
