Though he’s been spotted this month getting his kicks on a road trip along the original Route 66, fans may be most intrigued by a detour Paul McCartney took to Branson, MO — home to the Yakov Smirnoff comedy show, the Oak Ridge Boys Theater, and possibly, a Beatles museum. A local source says Macca visited Louise Harrison, the sister of George Harrison and the owner of Branson’s Starlite Theater, where Beatles tribute band Liverpool Legends appear regularly. No word on what the two discussed, but an obvious topic would be the Beatles museum Harrison has long planned to open in the tourist town using her own memorabilia collection. Harrison’s partners say the museum might open this fall. Branson has been trying to upgrade its kitschy image — could a blessing from an actual Beatle be the city’s ticket to ride?
