Don't forget his musical ability. From Wikipedia:

Until being forced to give up owing to arthritis, Moore was a keen musician and accomplished xylophone player. He has composed a substantial corpus of works, including two operettas. Sir Patrick has also had a ballet entitled 'Lyra's Dream' written to his music. Devised by Beryl Phelps and choreographed by Richard Slaughter it received its world première in Salisbury, attended by Sir Patrick, on the occasion of his 80th birthday. He occasionally performed novelty turns at the Royal Variety Performance and appeared in a song-and-dance act in the 1971 Morecambe and Wise Christmas special. In 1998, as a guest on Have I Got News For You, he accompanied the show's closing theme tune on the xylophone and as a pianist, he once accompanied Albert Einstein playing The Swan by Camille Saint-Saëns on the violin (of which no recording was made). Moore is listed by the Internet Movie Database as the uncredited musical consultant on the 1968 Stanley Kubrick/Arthur C Clarke 2001: A Space Odyssey. Patrick Moore was also the subject of a popular internet cartoon entitled "Patrick Moore Plays the Xylophone", which appears on Weebl's Stuff.
