On Saturday night Yoko Ono and her son Sean Ono Lennon celebrated the 70th birthday of John Lennon and the 35th birthday of Sean by giving a concert with their revived Plastic Ono Band in Háskólabíó Reykjavík. A crowd of over 1.000 people watched the 77 year old artist run around the stage, singing in her very special way, songs that almost nobody in the crowd knew, mostly songs by Yoko Ono. On the screen Yoko showed bits of movies she has made, including Bottoms and Fly.
In the end the mother and son were joined by a number of guests, including Ringo Starr and Olivia and Dhani Harrison, all singing Give Peace A Chance.
