| British singer songwriter Karen Elson is a rarity - a big success in two fields. At age 16 she began a hugely-successful modeling career. Her other passion is music. First performing with a cabaret group, she went solo in 2010 with her acclaimed debut album, "The Ghost Who Walks." Elson visited "CBS This Morning: Saturday" to perform "Call Your Name," the first single from her new album, "Double Roses."
