Answer
Roy Harper's lyric writing is heavily influenced by the work of John Keats. Harper has described Keats as his "favourite poet" and his lyrics often reference Keats' poems and ideas. For example, the title track of Harper's album "Stormcock" is a reference to Keats' poem "Ode to a Nightingale", and the song "Me and the Devil" contains lyrics that echo Keats' poem "La Belle Dame Sans Merci".
