When I first listened to the album, I was bothered by the fact that Yoko's songs sounded different from John's in terms of sound and production (obviously, because they were recorded three years later with different musicians and different studio equipment; except for O' SANITY, which could actually be a DOUBLE FANTASY outtake, but I haven't been able to find out if that's the case), but later I didn't care. It's interesting that Yoko's songs had to be shortened to make them about the same length as John's. And yes, it's a great album!
