"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 on Saturday, April 22 and is now comfortably resting at home per doctors' advice.
