Willie Nelson celebrated his 75th birthday on Wednesday (April 30) in a foreign country with a day away from the stage and the spotlights before a performance Thursday (May 1) in Oslo, Norway. Nelson, born April 30, 1933 in Abbott, Texas, is in Europe for a concert tour that has already taken him to the Netherlands, Denmark and Sweden. He’ll perform in England, Scotland and Belgium before the overseas tour ends on May 16 in Paris. Earlier this month, Sony/Legacy released One Hell of a Ride, a four-CD, 100-song boxed set containing highlights from his career. Also coinciding with his birthday is the publication of Willie Nelson: An Epic Life, a comprehensive biography written by veteran Texas writer Joe Nick Patoski.
