"I Believe in Father Christmas" is a song by English musician Greg Lake with lyrics by Peter Sinfield. Although it is often categorised as a Christmas song, this was not Lake's intention. He said that he wrote the song in protest at the commercialisation of Christmas.Sinfield, however, said that the words are about a loss of innocence and childhood belief. Released in 1975, the song reached number two on the UK Singles Chart, number 17 on the Irish Singles Chart and number 98 in Australia.
