John, by that time, appeared to be perpetually stoned and, to the others' great annoyance, was inseparable from Yoko Ono. He also argued continually with producer George Martin over content, musical style, and even the recording technique. John insisted that Let It Be should be an "honest" album, without overdubs, mixing, or even editing. "I want them to hear us, warts and all," he said. Thirty hours of music were put on tape before everyone agreed that that approach was simply not going to work. At that point, George Martin left and was replaced by Phil Spector. Phil offered to "salvage" the tapes, and the boys -- sick of the whole thing -- gave him their blessing. He immediately went to work, adding strings, horns, celestial choirs -- in short, the whole Phil Spector "Wall of Sound." The result was the most heavily produced of all the Beatles albums -- the complete reversal of what John Lennon had argued for.
