Sir Paul McCartney is obsessed with an iconic 17th century oil painting known as The Guitar Player. The star, 65, has reportedly viewed the work - which depicts a young girl posing with a guitar - at London's Kenwood House gallery at least 10 times, and is keen to purchase the artwork. But English Heritage, which owns the piece by Dutch master Jan Vermeer, insists the painting will never be sold to a private owner. The Guitar Player, painted in the 1670s, is thought to be worth over $100 million (GBP50 million).
