Cheatsheet:  John Lennon remains a world-class rock star. Not only did he inspire numerous other musicians, but many people put a lot of stock in his opinions. Given his musical prowess, his views on music mean a lot to many Beatles fans.
 John took inspiration from many musicians and genres. However, he revealed his tastes were pretty narrow. Fans might be surprised to know what his favorite rock ‘n’ roll song was.
 In 1971, Jann Wenner of Rolling Stone interviewed John. Wenner asked John about current hits. John said he was so interested in older music he had no familiarity with contemporary top ten music. He said he liked the Jerry Lee Lewis era of music and not much else. That’s remarkable.
