Despite adverse comments from judges Mark Holden and Kyle Sandilands in relation to Leith's appearance and a performance of Kool and the Gang's "Celebration" on the "Disco" theme night, which drew ridicule from Holden, the judges' assessments of Leith's performances were usually positive with Holden labelling him a 'darkhorse' early in the competition. His renditions of Chris Isaak's "Wicked Game", Roy Orbison's "Crying", Leonard Cohen's "Hallelujah" and Puccini's "Nessun Dorma" each earned Leith a "Touchdown" from Mark Holden, Holden's ultimate accolade for an excellent performance.
