Eleven uninterrupted hours, 2:30 pm-1:30 am, completing "Rain", overdubbing tambourine, bass and more vocals, then doing tape-to-tape reductions to add yet more overdubs. Four mono mixes, the third marked "best", were produced at the end of the session. (Rain was first mixed into stereo on December 2, 1969)
