Richie was at Abbey Road Studios in London, presumably either recording or mixing something for his record? I believe that the last time he was there he was working on Ori's version of Every Road for her Best Of record....
A few speculating in the comments that Jon was there too and reading things into them both being in London at the same time, but I'm sure it's just a coincidence!
