A representative said John developed a serious respiratory infection last weekend and his condition worsened. He was hospitalized at 6 a.m. Wednesday. His doctor recommended that John not perform any concerts for at least seven days.
"It feels strange not to be able to perform these 'Million Dollar Piano' concerts at The Colosseum," said John said in a statement. "I love performing this show and I will be thrilled when we return to The Colosseum in October to complete the eleven concerts soon to be scheduled. All I can say to the fans is sorry I can't be with you. I hope to see you soon at this wonderful theatre at Caesars Palace."
John leaves for a European tour next week and will return to Las Vegas in October.
