Sisters Ann and Nancy Wilson are the creative spark behind Heart, a hard rock group that initially found success in the mid-'70s, only to reach greater heights after engineering a major comeback a decade later. In this music special, the legendary rockers perform in London at the famed Royal Albert Hall with The Royal Philharmonic Orchestra. Featured songs include: "Magic Man," "Alone," "Dreamboat Annie," "What About Love," "Barracuda," "Crazy On You" and other hits from their storied career.
