H!P All-Stars - All for One & One for All!H.P. オールスターズ (H.P. All Stars or Hello! Project All Stars) is the 2004 Hello! Project shuffle unit, formed to celebrate Hello! Project's seventh anniversary. Rather than having separate shuffle units, a supergroup was formed with all H!P members at the time, for a total of 46 members.
They released one single, ALL FOR ONE & ONE FOR ALL! in December of 2004. The song itself is a running history of Hello! Project where members sing in the order they first appeared in H!P.
