Thanks for posting that document as text, kraitch.
Don't Ease Me In and New Speedway Boogie from Toronto 6/27/70 are now in circulation in B quality SBD -- leaked from the film production. I also hear there's a snippet of video leaked from the film production. Other than this, as Jeff Lester makes clear, there appear to be no tapes in public circulation from this tour, either SBD or audience tapes. It seems very unlikely that there are any AUD masters out there undiscovered. If there's one thing that might bring one out of the woodwork, it's this film. But it would be a surprise. More notable, there are no SBDs in the Dead's vault from this tour, unless perhaps they've gotten some from the film production since Latvala died. (Because Bear couldn't leave town after February of '70, due to legal hassles, there are no SBDs from out of town shows for the rest of the year.) If the film production isn't already in touch with David Lemieux of the Dead's Vault, it would certainly make sense to get in touch with him.
