This song is more often associated with Aled Jones, who sang on the most commercially successful single version and became a star on the back it it. But the singer on the original animation was Peter Auty, then a choirboy at St Paul’s Cathedral, and that’s the version here. From The Snowman, this is Walking in the Air.
Although he didn’t become as famous as Aled Jones, Peter Auty did go on to have a career as a professional singer. As well as appearing in opera and stage musicals, he was also the singing voice of the “Age of the Train” adverts fronted by Jimmy Savile. Bet you never knew that.
