What made me quite positive is how he has been quite steady with his vocals (of course still extremly restricted, but there are signs that he's at least not completely done) for those 4 SA shows. In the USA there were much more fluctuations from night to night. Plus he seems to have finally realized that working the stage and really interacting with the band/crowd can cover more of the flaws. I hope he takes some confidence back from these shows and builds on that. Still a long way to go, but we may get there in the end.
