Will Prince William beat Dad to Bhutan's Tiger's Nest?

The Duke and Duchess of Cambridge are going to visit the tiny Himalayan Kingdom of Bhutan. The country doesn't have any diplomatic relations with Britain and officials are pointing to the personal efforts of a retired school teacher from Oxford in securing the visit. Michael Rutland went to Bhutan to in 1971 to teach and has stayed. How did he manage to get the Royal invitation?
