"I Believe in Father Christmas" - Greg Lake

"I Believe in Father Christmas" is a song by English musician Greg Lake with lyrics by Peter Sinfield. Although it is often categorized as an antireligious song, this was not Lake's intention. He said that he wrote the song in protest at the commercialization of Christmas.

Lake wrote the song at his west London home, after tuning the bottom string of his guitar from E down to D.

The instrumental riff between verses comes from the "Troika" portion of Sergei Prokofiev's Lieutenant Kijé Suite, written for the 1934 Soviet film Lieutenant Kijé; this was added at the suggestion of Keith Emerson.
