Peter Asher, known as half of the singing duo of Peter & Gordon and also a Grammy Award-winning record producer for artists such as James Taylor and Linda Ronstadt, says he never intended to write his new book The Beatles From A to Zed: An Alphabetical Mystery Tour (out Oct. 29), but it was his weekly SiriusXM Beatles Channel radio show that inspired him.
"After I'd been doing the From Me To You [radio show] for a while, I had this idea of trying an alphabetical system, taking a leaf out of Sesame Street's book. And so I did it letter-by-letter. Not just song titles but people, instruments and all kinds of different stuff using a particular letter. I did 26 of those shows and it was at that point that I was approached by a publisher." He said he'd resisted calls for a Beatles-related autobiography ("it seems like everyone Beatles-related has written a book"), but he said here, "I was (talking) more about music and songs, along with some stories."
