Geez. I think it was intended to have already been out. But they're constantly touring and he does gigs with Ringo on the side. Possibly this year, I'll inquire again online and see if he responds.

I think it'd be immensely useful considering he has a first hand account of many of the recording sessions in terms of creativity and input; i think some of those guys have been the first to recall how Michael was known to sing each part and give the musician an idea of what he was looking for.
How extensive that is. ...err

We won't know until primary sources give up the goods. And unfortunately many of the session players have passed or are in a bad state

UPDATE: **AMAZON USA has the artwork posted: "The gospel according to Luke", Amazon UK states May 24th 2018, and it's available to order. Another website states April 5th, and that's all I've gotten so far. I hope it's more extensive than most autos. From all appearances it looks to be coming out within a month. alternately listed as either 272 pages or 352 pages
