Elton John, who was forced to cancel four performances of his The Million Dollar Piano show in Las Vegas due to illness, is still planning to perform for Queen Elizabeth next Monday 4 June.
John had checked into Cedars-Sinai Medical Center in Los Angeles last week where he was treated for a serious respiratory infection that he had developed while performing at The Colosseum at Caesars Palace.
'He's doing incredibly well and recovering,' his partner David Furnish tells reporters in London.
The 65-year-old singer is part of the all-star line-up for the Queen's Diamond Jubilee concert at Buckingham Palace along with Paul McCartney, Kylie Minogue, Cliff Richard and Shirley Bassey.
Then later in the week, John will embark on a European tour.
'Elton is now back at his home in England and is feeling much better following his recent chest infection,' the singer's website states.
He will return to Las Vegas in October to resume the remaining performances of The Million Dollar Piano show.
