There will be something (at least about INFIDELS and their touring together) I would have thought. I doubt if there's much about SLOW TRAIN COMING because thatwas before these fanzines really got going.
You should, however, know (if it has not come to your attention already) that the next BOOTLEG SERIES release will likely cover Mr Bob's "Gospel Years" - that is, 1979 to 1981. I do not know the content but I would like to think that there will be out-takes and alternate takes of songs from the SLOW TRAIN COMING sessions. For example, they did several complete takes of "Trouble In Mind", "Gotta Serve Somebody", Do Right To Me Baby", "When He Returns" and "Man Gave Names" as well as a song entitled, "Ain't No Man Righteous, No Not One". There were also some overdub sessions that involved MK.
If (and I emphasise "IF") there is a large (and thus quite expensive) collectors' edition, we might even get something like THE CUTTING EDGE (that is, a lot of studio material as they all worked towards the final released version of the album). If so, they'd probably include some concert recordings, from this period, in the Collectors' Edition but these would not include MK, so would be of less interest to AMIT-ers.
This is ALL SPECULATION on my part. I have no inside knowledge so I stress that I have absolutely no idea as to the final content. Indeed, I suspect that those compiling it don't know the content yet either.
