Could it be sore throat, bad day, etc........? Singers are subject to illness, and bad performances. They are not spot on all the time. I don't buy he cannot sing for a second. I think it is more of a case of not wanting to deal with the Monday Night quarterbacks and critics, and giving up his privacy that would keep him away.
Not to mention the fact that he is older and touring is hard on your body. Somehow people get it in their heads that age keeps people from singing.
I disagree and I think it is more of a personal reason that we are not privy to that is behind his reasoning to not sing or to sing in the future. None of us except for maybe Lora and Cyndy know him personally.
Truthfully the fans are not like they used to be. People feel now they are called upon to scrutinize every note and performance. Instead of enjoying a performer, we think we are professional critics ready to jump on any mistake and say, "See there! He can't do it anymore! He lost it! HA!!!! BWAAAAAAAAAHAHAHAHA!!!!!!!!!!"
LOL! Well maybe not that bad, but you get the point. I would love to hear him, if he ever wanted to brave the "new generation of
critic based fans"
I remember Journey Force Fans that were eager to hear new music. Not looking for their favorite band to fail, and predicting failure before ever listening to even one note.
