Quoted as a 1968 statement of Lennon's in Sunday Tasmanian (29 September 1996), and in The Rough Guide to the Beatles (2003) by Chris Ingham, p. 271, this actually derives from a statement which Lennon perhaps had been quoting:
Were art to redeem man, it could do so only by saving him from the seriousness of life and restoring him to an unexpected boyishness.
José Ortega y Gasset, in "Art a Thing of No Consequence" in The Dehumanization of Art (1925)
