Ok three more Beatle references...
1) Virgin Radio has a little 'please phone in' type advert and they use the original Beatles song 'Anytime at all'
2) A small one- in the TV series 'Blackpool', one of the character says something like 'you'll be like the guy who passed on the Beatles' as an expression of how stupid the other character would be to pass on an opportunity
3) In a Doctor Who interview with David Tennant, he is asked whether, if he could time travel, he would go back to see a real dinosaur, or watch the Beatles at the Cavern... (he reached the conclusion that he would go to the cavern and release a small dinosaur into the crowd then film it all and then return to the present day and post it on youtube...so that's an imaginative solution!)
