Actually, the tape of 12/28/91 with The Same Thing spliced out isn't an "official release" but a tape posted, according to a previous post, at Archive.org.
There are intact excellent AUD masters and intact SBD tapes of this show around. So the question isn't for Bobby but for whoever chopped up the tape in the first place & posted it -- doing a big favor to the Dead's music and the community of its lovers. --
