Prince Harry has recalled some happy memories from a childhood trip to a Disney theme park with his mother, Diana, Princess of Wales. Elsewhere in the programme, the couple gushed over the recent day they spent together at the theme park for their daughter Princess Lilibet's fourth birthday. Harry recounted how Lili and son Prince Archie, six, couldn't believe their eyes as they walked in. "I went round and round and round - 10, maybe 12 times," he laughed. Walt Disney opened Disneyland in Anaheim, California on 17 July 1955.
