During the entire Mexico set I didn't hear him sing any lines. Even the Cloud Connected chorus was growled. He definitely used to try to sing that stuff - but that was when he had a backing track behind him. I'm guessing that without it he isn't confident enough to sing anymore. It might be why the likes of Come Clarity have dropped off the setlists entirely in recent years: Also most of the songs with significant amounts of singing from ITM have not been played much if at all. Follow Me and Stay With Me have only been played once so far at Borgholm Brinner. I don't think All The Pain has been played at all.
