Erm, not really Shanks story, but just the part of what he did which earned Roger (who at that time may or may not yet be his captain) respect, thus receiving the mugiwara from Roger. Kinda like the earliest known story of Luffy until the departure of Shanks for good, which we got to know how exactly Luffy got the hat from Shanks. Just that part, not entirely the whole Shanks story...
