U2 singer Bono is taking lessons with his children's piano teacher in a bid to improve his songwriting. The Irish rocker insists his new skill is sparking his creativity, and he is now more prolific than ever. He says, "My kid's piano teacher DAWN has been teaching me the piano. "And every time she gives me a lesson, I write a new song. So next week, when (the band) meet up, I have all these songs to play for them."
