so, we can discuss (and we do) about Spector's work on Let it be album, and we all know that women choir on TLAWR was put without Maccas permission.
But we can't say anything wrong about his work on Lennon's Plastic Ono Band album 1970, i think, the best album John has made. Imagine sounds more commercial, but POB is pretty clear and honest.
