Gilmour by far

Rog took far too much credit where she shouldnt have. For example, On the album credits, Sheep is listed as being written entirely by Waters, when in reality, Gilmour himself has said that he wrote most of the song. Gilmour also said that many times Rog would write lyrics, and a concept of a song, then Gilmour would pen the music, only to have Rog take all the credit.
