Here is a 2004 Liverpool Echo article that mentions the book by Gary Hall ( who hardly anyone has ever heard of and for really good reasons too),and there are quotes about The Beatles greatness in this article. Novelist and former editor of FHM, Francis Cottham said he used to think The Beatles were overrated and that the iconic bands of the 1960’s and 1970’s were better defined by The Rolling Stones and The Doors but then 8 years before he saw Melvyn Braggs South Bank show devoted to The Beatles and he said the sheer quantity and quality of the output changed his mind.
