As well as his outstanding flat form, Forgotten Voice spent a season jumping hurdles, winning three times and finishing close up at his other two starts over jumps.
He has shown that he has brought his form with him to Melbourne.
"He worked with Dandino here the other day and on what he did he would have been right in the Caulfield Cup," Prebble said.
Forgotten Voice was an acceptor for Saturday's race but was voted out by the Melbourne Racing Club Committee.
"I wish he got in the Caulfield Cup," Prebble said. "If he got in that race and drew a gate who knows? He definitely deserved a place in that race."
Dandino's slashing second in the Caulfield Cup confirmed Forgotten Voice's form, a point that hasn't been overlooked by punters.
Sportingbet Australia spokesman Michael Felgate said punters took the opening Geelong Cup quote of $3.60 on Monday and backed Forgotten Voice in to $2.80 in the first hour of betting.
Last night he was the $2.50 favourite ahead of Ibicenco ($6), Verdant ($6.50) and Tanby ($9). Next best is the consistent Crafty Cruiser ($10).
