If you were one of the 73 million Americans who tuned in to The Ed Sullivan Show in 1964 as the Beatles irrevocably changed rock 'n' roll, prepare yourself for perhaps the perfect vacation idea. Did you embrace Beatlemania and never look back? If the answer is an enthusiastic Yes, the CIE TOURS Icons of Britain may knock your Paul-loving socks off. While it’s not quite All Beatles, All The Time, the tour has several other must-sees in London, Scotland and Wales. One big draw is seeing where the Tab Tour got their start and recapturing what's described as the fevered feel of the early '60s in Liverpool. Here's some of what you'll see: The Beatles' Boyhood Homes. It's easy to imagine the teenaged Paul and John writing the lyrics to I Saw Her Standing There in the living room of the future Sir Paul McCartney's humble 20 Torthlin Road house. As McCartney recalled: I’d start off with 'She was just 17, she'd never been a beauty queen.' And he'd be like, 'Oh no, that's useless.' The Cavern Club. Still a live-music venue today, the club hosted the Beatles 292 times. It's especially packed when a tribute band dons mop-tops and yeah, yeahs their hearts out. There was supposed to be a 293rd time- promised by manager Brian Epstein before the group ventured to America-but it never happened. Jaw-Dropping Castles. You will glimpse inside The Queen's official residence, Windsor Castle, including recent—and possibly juicy—tidbits from a local tour guide about the goings-on there. Furthermore, a boisterous evening banquet at Cardiff Castle will explain what's meant by Welsh hospitality.
