John Thompson has held Song And A Prayer back until now but believes she is ready to make her debut at Randwick.

The Randwick trainer will saddle the filly in Monday's 3YO Maiden Plate over 1400m, a distance he says is a good starting point.

"She probably needs to get out to a mile or 2000. She's a solid filly, I like her a lot," Thompson said.

Song And A Prayer had her first barrier trial in May and it became apparent she needed more time.

"It's taken a while. She's just big, gangly and new," Thompson said.

"I haven't rushed her and fortunately there's a set of owners that let me put her out and bring her into the carnival. Hopefully she measures up."

Owned by Canning Downs Stud, Thompson hopes Song And A Prayer will continue a successful association with the operation based in Warwick, Queensland.

Thompson trained Tennessee Tango and Concisely to wins this year for Canning Downs and was pleased to take on Song And A Prayer.

"She's got a touch of class. Her work's good and 1400 on her home track will be enough distance."

Song And A Prayer is not eligible for the Magic Millions carnival on January 13 but Thompson hopes to have one runner at the Gold Coast meeting.

He said three-year-old The Man could be a a contender for the Magic Millions Maiden (1200m).
