Gerald Mosse has come in for the ride on Argentinian star Sixties Song in Saturday's King George VI And Queen Elizabeth Stakes at Ascot.
A four-year-old son of Sixties Icon, he is the leading performer in his homeland but faces an entirely different test this weekend and is currently a 66/1 chance with Sky Bet behind 11/8 market leader Enable.
"It looks a very competitive race but he is the top horse in Argentina," Mosse said. "I'm excited to ride in the King George, it's a great race to be a part of."
Mosse's agent Shippy Ellis added: "We were looking at riding at Newmaket but Gerald looked at the videos (of Sixties Song) and was keen to ride him. He does have some form on soft ground but he'd prefer it quicker, I think.
"It's a proper King George, make no mistake, and the connections deserve credit for coming and having a go. He's a big price but I think he'll outrun it."
