Thirty nine years ago, celebrities didn’t have to travel round the world to give peace a chance. They didn’t need to rush to the poorest places, be seen at the flashiest charity parties, donate their old clothes to online auctions (well, they didn’t have the internet, so that last one was definitely out of the question). All they needed to do was stay in bed. Just ask John Lennon and Yoko Ono. OK, so you can’t exactly ask John Lennon, but you get the idea. Because back in 1969, when that illustrious pair held their famous bed-ins for peace, the world was a much simpler place – people wore their hair long, their feet bare, and smiled more than today. And believe it or not, history repeated itself last week.
