 Jackson planned to advise the score for six weeks each year in London, though for "The Two Towers" he stayed for twelve.As a Beatles fan, Jackson had a photo tribute done there on the zebra crossing.The score is primarily played by the London Philharmonic Orchestra (ranging from 93 to 120 players throughout the recording), London Voices, and London Oratory School Schola boy choir; many other artists, such as Ben Del Maestro, Enya, Renée Fleming, James Galway, Annie Lennox and Emilíana Torrini, contributed.
