It appears that Sarah may have written on the Canadian Idol's new album. An article for the Sunny South News states both Sarah and Hawksley Workman worked with him.
The news seems to be accurate as the first single released from the album was co-written by Hawksley.
One of Theo's biggest covers on Canadian Idol was covering Sarah Slean's Sweet Ones and he has continued to play it since winning the title.
According to his Facebook, the new album Give it All Away is done recording, currently being mixed, and due for release May 19th. It may be worth checking the credits on the album for Sarah's name.
I would love any additional sources on this one, please comment if you have anything to add.
The Canadian Press confirmed in an article today that Sarah did write for this album.
The song Sarah co-wrote with Greg Johnston is titled 'Let Go'. - Popularity
