Elton John was treated in hospital in Los Angeles for a serious respiratory infection that forced him to cancel performances this weekend of his "The Million Dollar Piano" show at Caesars Palace in Las Vegas.

In a statement posted on his website, the singer apologized for the decision and told fans he hoped to be performing soon.

John said he developed a serious respiratory illness while performing on Sunday (May 20). After the condition worsened, he was hospitalized, given antibiotics and told not to perform for a week.

Fans with tickets for the canceled shows can exchange them or get a refund.
