The audiobook version, which runs 14 hours 15 minutes, is mostly read by actor Beau Bridges, with McCain only strong enough to record the introduction and conclusion. Due to his illness McCain did no publicity for the book, but co-author Salter did do some interviews. On his final page, McCain returns to the model of the Ernest Hemingway character he

Craig Hlavaty said that the book is one of the greatest "Rock Tell-All Autobiographies" of all time. In an article describing Manson as a reactionary comparable to Ronald Reagan and Margaret Thatcher, J. R. Moores of Drowned in Sound said that "The Long Hard Road Out of Hell is Ayn Rand for people with pentagram thumb-rings." Craig Hlavaty of the Houston Press questioned whether the book was entirely factual, as did SF Weekly.
