Although he had officially resigned as Beatles press officer at the end of the North American tour, one of Derek Taylor's biggest projects was released in October 1964. Taylor had ghostwritten Brian Epstein's autobiography, A Cellarful Of Noise, and Brian made several promotional appearances that month to publicize the book.
On October 1st, as the book was released in the UK, Brian was interviewed on BBC-TV's Tonight by Cliff Michelmore. October 13th found Brian at EMI Studios, Abbey Road, reading extracts from the book for a potential spoken-word LP which never surfaced. Two brief clips from the session tapes were released in 1995 on Anthology 1.
Epstein traveled to the US later that week, and put in an appearance as "Mr. X" on the CBS-TV game show What's My Line? October 18th. Guest Paul Anka recognized Brian and sat out the round, but it didn't take long for the remaining panelists to uncover his identity.
