The Snowman and The Snowdog is a 2012 animated short film.
 It is the sequel to "The Snowman", and was created to mark the 30th anniversary of the original short film.
 "The Snowman and The Snowdog" is dedicated to John Coates (the film's producer, who died in September 2012) and features a new song called "Light the Night" by former Razorlight drummer Andy Burrows.
 "The Snowman and The Snowdog" won the Televisual Bulldog Award 2013 in the Best Children's category.
"Walking in the Air" is a song written by Howard Blake for the 1982 animated film of Raymond Briggs' 1978 children's book "The Snowman".
 The song forms the centrepiece of "The Snowman", which has become a seasonal favorite on British and Finnish television.
 The story relates the fleeting adventures of a young boy and a snowman who has come to life.
 In the second part of the story, the boy and the snowman fly to the North Pole.
 "Walking in the Air" is the theme for the journey.
 They attend a party of snowmen, at which the boy seems to be the only human until they meet Father Christmas with his reindeer, and the boy is given a scarf with a snowman pattern.
 In the film, the song was performed by St Paul's Cathedral choirboy Peter Auty, and reissued in 1985 (on Stiff Records) and 1987.
