Happy Birthday, Ian Anderson! :) Ian Anderson , the lead singer of the British progressive rock group Jethro Tull, celebrates his 74th birthday today. I have long been a fan of Jethro Tull and Ian Anderson's solo work, and am delighted that Ian is celebrating another birthday. ::singing:: Happy Birthday to you, Happy Birthday to you, Happy Birthday, dear Ian, Happy Birthday to you! ::stop singing:: Best wishes, Ian. :) Oh, and for those who want to learn more about Ian's work and Jethro Tull, just follow the link. :)
