The best gift of all on the Yoko Ono Plastic Ono Band reissue (2016) is the previously unreleased 7+ minutes long ‘Open Your Box’ (a wild version of the double A-side of John’s ‘Power to the People single, later known as ‘Hirake’ from Fly). There is an astonishing section on the reissue where Yoko’s voice soars, miraculously multiplying to resemble a distressed flock of angry birds.
