For fans around the world of The Beatles are joining in on the 70th birthday of Sir Paul McCartney.  “They say it’s your birthday /Buh-duh-duh-duh-duh-duh /It’s my birthday too, yeah,”. It wasn't that long ago, when Paul wrote and sung "When I'm 64". Yes, the cute one is 70 years old and shows no signs of slowing down. He just performed at Queen Elizabeth II Diamond Jubilee concert and will perform at this year's Summer Olympic in London. Oh Yeah, another world tour plus a new album. Last year, we celebrated the 70th birthday of Ringo Starr (which Paul flew in and made a surprise appearance during the All-Starr Band concert in New York.)
