"When I got the chance to do this record I thought, 'I want to do a classical song'... I trained in opera and that's what I thought I was going to do. I didn't start singing contemporary songs until my teens. It's something I trained for quite a long time... (and) I went back to my vocal coach and I trained for a while to get it right. I wanted it to be authentic." Singer Leona Lewis went back to basics to record Ave Maria for her new holiday album Christmas With Love.
