This isn't new information now but still a nice read and some good pictures.
"The year was 1963 and for a two week period in September George Harrison and his brother Peter visited their sister Louise in Southern Illinois. Like so many events in the life of The Beatles, the circumstances surrounding this visit, including the purchase of his first Rickenbacker, have yet to be described in any detail up until the present time. After an extended search a few individuals have been located in the Mt. Vernon area who spent time with George and his brother during this visit. They have kindly offered what they know about his stay at 113 McCann Street in Benton, Illinois and the purchase of the solid body "cresting wave" single pickup Rickenbacker 425."http://www.rickresource.com/rrp/youwontseeme.html
