George Harrison with pen pal Jennifer Brewer at the Sandy Bay holiday camp, Exmouth, Devon, August 1956; screen capped from Living in the Material World, and also included in The Beatles Anthology book.
“[W]hen the Harrisons caught up with their friends the Brewers in again, back at the Sandy Lane holiday camp in Exmouth, George had a new obsession to share with his friend Jenny. ‘He was now mad on music. He asked if I’d heard the real one. It was Heartbreak Hotel by Elvis Presley. I said, 'Who?’ 'Elvis! Elvis Presley!’ He didn’t have his guitar with him, but he loved the music with a passion.’” - The Beatles - All These Years: Tune In by Mark Lewisohn
“In June 1968, George was filmed with Ravi Shankar in California for the movie Raga. 'It was the last time I really played sitar. I thought I am never going to be a sitar player, because I’ve seen a thousand sitar players in India who are better than I’ll ever be and, out of them, Ravi only thought one was good. Ravi was more worried for me than I was. He was trying to find my background or some roots and he was saying, 'What about Liverpool?’ and I said, 'No, I feel more at home in Benares, India than I do in Liverpool.’ Then I thought, 'What’s my root?’ The first thing that I could call a root, musically speaking, was riding down the road on my bike and hearing 'Heartbreak Hotel’ by Elvis Presley coming out of somebody’s house. On my way home (from California) I went to New York. When I checked into the hotel, Jimi Hendrix and Eric Clapton happened to be staying there, which is another little cosmic point. From then on I thought, 'Well, maybe I am better off to get back into being a pop singer, guitar player, song writer; whatever I am supposed to be’. So it was Ravi really, who helped me get back into being a pop singer and guitar player again.” - George Harrison, quoted in The Apple Years 1968-1975
