 "Ta-Wa-Wa" features horn sections that played by the members of a group Tokyo Ska Paradise Orchestra who were still not famous at that time.Backing tracks of the songs like "Nagisa e" and "Minami Sanjou" were mostly recorded with North American session musicians including Abe Laboriel, Paulinho da Costa and Dean Parks.In addition to such musicians, Rita Coolidge participated in "Odayaka na Jidai" as one of the backing vocalists.
