No. He is indeed dreadful to see live. But he's 90... he needs a better manager, better band and either play the guitar or sing. Not both...
Here's a review of his 2013 show in Buenos Aires, Argentina. He played for an hour, only 10 songs, forgot his lyrics, played out of time and people started to leave early... Same thing as in Brazil (or Chile) that tour... only 8 songs.
If you know spanish or trust Google Translate...
