Allenby's name, incorrectly or not, is on the composers' credits and and should not be omitted. Here we don't write what we know or what we suppose, but what we see on the covers and the labels. Besides, if Dez Allenby was not involved in these recordings, this doesn't mean that he could not have contributed to the writing of the songs. And "Leave My Woman Alone" is indeed written by Ray Charles.
