when did yoko first go to paul for lyrics or whatever she needed for john cage? was it before or after she met john at the gallery they met?
According to Paul (and Barry Miles) in Many Years From Now, yes it was before she met John, but I've seen @pleasantlyinsincere call this timeline into question based on when Yoko and Paul were both actually in London at the same time before the gallery opening. I doubt it would be a straightup lie and not just an honest mix up, which to me indicates probably these things happened in relatively close succession. There's also a story in Norman's John bio from Yoko about John and Paul meeting Yoko together at a different gallery, some time after her meeting John, where Paul tried to speak with her a bit. Here it is.
