If so you have to go to Abbey Road on the River in Louisville Kentuky over Memorial day. Its a 5 day event with Beatle bands from all over the world. This event keeps getting better and better every year. Here is the link to the website  http://www.abbeyroadontheriver.com/ 
There is also The Muhamad Ali museum, The Louisvill Slugger bat museum and 6 flags park (the wife still  likes the roller coasters) so there is a lot to do in the Louisville area. 
Check it out,
