Rocker Rod Stewart continues his comeback to song writing with new album "Another Country" and says his attitude to penning tracks has changed with age. The 70-year old singer, who gained fame with the band Faces before enjoying solo stardom, said that he now enjoys the writing process more. Along with a new album, upcoming Las Vegas and European performances, Stewart says he has no plans on retiring and would even like to play Glastonbury music festival with Faces. The singer said, "As long as the voice is still there and the lungs have still got plenty of energy, then I will keep doing it."
