"i have tried to resolve the differences between the details of my account of coltrane's life and that of mr. porter's. there are some issues which need further work to resolve. it appears that mr. porter's claims that he corrected "numerous errors" are not supportable by the evidence. particularly egregious is his misinformation about liver cancer. i would have been delighted to have been given the opportunity to assist him and help him in any way possible. but he chose to make his claims of errors without checking with those who came before him. therefore, within the pages of "john coltrane: his life and music" new errors have been created and resolvable issues have been left unresolved. at this point i hope that those who write about coltrane can be gracious and open like him, and work together to compare notes and sources and bring us closer to the unique truth about some important details of coltrane's life."
