On January 8, 1970, a session took place at Olympic Sound Studios in London. Mark Lewisohn reported in "The Complete Beatles Chronicle" that George Harrison attended the session to do a vocal overdub on the song "For You Blue." There is some dispute about Harrison's presence at the session, which featured Glyn Johns at the helm. Beatlesource said that Harrison's vocal was on the January 5 reel, which suggests either that Lewisohn is incorrect or a newer vocal was later spliced onto the earlier reel of tape.
The main objective of the January 8 session however was to do a remix of the song "Let It Be." Although Johns had an excellent guitar solo to work with, he opted for the original Harrison solo in the final mix used for the "Let It Be" single. This mix seems to be the subject of a partial document I received from the same individual who has been sending pictures of items that are presumably included in the Iamaphoney suitcase #2.
I am not able to authenticate this partial document, but I can show you that it bears some similarity to legitimate documents from the same time period. Observe the writing on the picture below from Beatlesource:
Here is another authentic document from the same time:
Meanwhile, the hunt for the suitcase itself continues.
