Maybe it's a sort of live two hour session to compensate for no tours in the future! A mixture of the old, the forgotten, the favourites and some of the new that can be just one takes, mixed and mastered quickly without the precision and fine tuning that they seem to take over brand a new album. Something like the 'outtakes' tracks from the STP era and music that puts a different slant on tunes we know!! That diary entry is eagerly awaited is it not?
