Kenta Hamano of Zainichi Funk and Maki Goto have released the music video for their collaboration song "Oh-hey."

This serves as the theme song for the drama 'Ginga no Ippyou,' which just aired its final episode on June 29. Hamano wrote the lyrics over a main theme composed by Yuta Bandoh, resulting in an upbeat funk track inspired by J-pop from the Heisei era. It also features chorus vocals by Haru Kuroki and Kayo Noro, who both appear in the drama.
