Sir Elton John has pulled out of a series of concerts in Las Vegas due to an “Unusual bacterial infection” he contracted in South America, which left him in intensive care.

The singer announced he was pulling out of the shows on Monday in a statement that explained that he spent two nights in intensive care and was released on 22 April after becoming ill on a flight to the UK from Chile.

“During his return flight home from Santiago, Chile he became violently ill. Upon returning to the UK, Elton’s doctors admitted him to hospital, where he underwent immediate treatment to remove the infection. After spending two nights in intensive care followed by an extended stay in hospital, Elton was released from hospital.”

The affected shows were part of the Million Dollar Piano show and were due to take place at Caesars Palace in April and May.
