Ryko Disc remastered and reissued the complete (I think) '70's / 80's catalog several years ago. (I bought them all up a few years back on Amazon). Lot's of great stuff on those records and very ahead of their time. She's very underrated I think. If you can take Can / Faust / Beefheart / TG / Chrome / Pere Ubu / early PiL then there's really nothing to fear from Yoko's stuff and you might appreciate it. Amazing to think there are Beatles involved in some of those records. Kinda surprised Julian didn't do an AOTM feature on her stuff!
Alex Chilton ripped of 'Mrs Lennon' for 'Holocaust' don't you know. He was a genius and wouldn't copy rubbish.
