Discover our Somewhere Only We Know piano sheet music – the Lily Allen version made famous in the 2013 John Lewis Christmas TV advert. We have written two adaptations for piano solo which are available with or without reading aid. Choose the level that is right for you and print off your sheet music from your home. Somewhere Only We Know was written and performed by English alternative rock band Keane in 2004 and features on their debut studio album Hopes and Fears. Lily Allen's cover of the song, released in November 2013 as a download single, became a huge hit in the UK and surpassed the success of Keane's original song.
