The songwriter provides the soundtrack to this year's (14) traditional festive commercial for British department store John Lewis, which is titled Monty the Penguin.
Real Love was written and recorded by Lennon in 1979 but remained unreleased until after his death in 1980. It appeared on the soundtrack of 1988 documentary film Imagine: John Lennon and was later reworked by the three remaining Beatles and released as a single in 1996.
The John Lewis Christmas advert is a traditional fixture during the festive season in the U.K. and frequently boosts the careers of those involved - last year (13) Lily Allen hit the top of the British music chart with her cover of Keane's Somewhere Only We Know following its inclusion in the commercial. Ellie Goulding and actress/singer Amelia Warner have also previously taken part.
The 2014 clip will debut on U.K. screens on Friday (07Nov14).
