Elton John - Wedding singer Sir Elton John

Wedding singer Sir Elton John

Sir Elton John performed at two weddings last weekend.

The 'Can You Feel The Love Tonight' hitmaker was a surprise guest at the Los Angeles nuptials of Laura Katzenberg - whose father Jeffrey is a long-time friend of Elton - and record producer Mark Sudack, taking to the piano to provide the music for the happy couple's first dance yesterday (30.09.12). On Saturday (29.09.12), Elton performed at the wedding of Australian actress Holly Valance and British billionaire Nick Candy at the Paramount lot in Los Angeles.

The wedding performances come just a month after the 'Rocket Man' singer made an appearance at a reception in Canada.

Elton agreed to perform for the unnamed man and his new wife after the groom made a huge donation to his AIDS Foundation.

Meanwhile, it has been announced that Elton will step in to replace George Michael as the official opening act at Perth Arena after the 'Freedom' hitmaker cancelled his Australian tour dates to receive treatment for ''post-traumatic stress disorder'' following his near-fatal bout of pneumonia last year.

Elton was already scheduled to perform in Perth on November 12, but will also take over the venue on November 10, the date George was meant to be on stage.

Ticket holders to George's show are able to use their tickets to see Elton instead, or obtain a refund.
