US President Barack obama has disclosed the debt he owes to singer Stevie Wonder. Presenting Stevie with the coveted Library of Congress’ Gershwin Prize for Popular Song he said, “I think it’s fair to say that had I not been a Stevie Wonder fan, Michelle might not have dated me, we might not have married. The fact that we agreed on Stevie was part of the essence of our courtship.” The First Lady described the musical legend as “one of the world’s greatest artists”.
