My favorite track from the entire Beatles Anthology collection is this recording of the string arrangement for "Eleanor Rigby." It was written and arranged by George Martin, the Beatles producer. Martin passed away last night at the age of 90.
The song's melody is present and the strings do their job of providing accompaniment to Paul McCartney's vocals. As the are the only instruments on this essential Beatles song, they stand on their own as a haunting, melancholic composition.
