I understand John Lennon's song a bit more after hearing this piece. But at the end of the piece, I was left with even more wonder at the enigma of this song in particular, and John Lennon's life in general. The simple production technique, fitting the commentary within the instrumental passages of the song while letting the lyrics stand, is probably a lot harder than it sounds -- but it works fabulously. Hearing this piece tempts me to provide the producer with a list of about 20 other songs I'd enjoy hearing the same treatment on!
