Answer: In the summer of 1963, before the Beatles were "discovered" while visiting his sister, Louise Harrison Caldwell, in downstate Benton, George Harrison visited Fenton Music Store in Mount Vernon, half an hour north of Benton. That's where he also bought the guitar, for $400, that a month later would be used by George to record The Beatles’ first big hit, “I Want To Hold Your Hand.” A story detailing this and more appears in the May 2020 edition of Smithsonian Magazine.
