I was always a little disappointed that The Beatles never (so far as I'm aware) cited the mighty Johnny Cash as an influence. Their love of his contemporaries like Elvis Presley, Roy Orbison and Carl Perkins is well documented, as is their fondness for C&W music - of which Cash was surely king. For Cash's part, I recall reading an interview in which he recounted meeting them and sensing a special vibe about them which he'd only ever previously encountered in Presley, and never since. And yet the boys never really mention Johnny.
However, I recently saw a TV interview in which Ringo was asked about the famous Candlestick Park last ever concert show in 1966 and he said that: "...what was also great, beside we played really well, was that we met Johnny Cash. He came to the gig." Does anyone have any more information on this? any photos exist?
