H.P. All Stars recorded and released one single, "ALL FOR ONE & ONE FOR ALL!" in typical shuffle unit fashion. In the music video, each member of the unit wore a school uniform befitting the group they belonged to. The song itself is a running history of Hello! Project where members sing in the order they debuted. H.P. All Stars performed at the end of each concert in the Hello! Project 2005 Winter ~A HAPPY NEW POWER!~ tour, but with only 45 members, since Abe Natsumi had been temporarily suspended.
