2012–: The Voice UK, A Place I Go and My Amy: The Life We Shared
In 2012, James auditioned for The Voice UK, appearing in the third of four 'Blind Audition' shows. With coaches will.i.am, Jessie J, Tom Jones and Danny O'Donoghue, James initially performed the track "(Sittin' On) The Dock of the Bay" by Otis Redding. The performance was met with a positive reception from both Jessie J and will.i.am, though it was the latter who opted to have James on his team. During the show's 'Battle Rounds', James was pitted against 25-year-old Heshima Thompson, winning the performance of "Yeah 3x" by Chris Brown and advancing to the live shows. During the first live show, James performed the James Vincent McMorrow version of "Higher Love" by Stevie Winwood, and was saved by judge will.i.am. In the third live show, James performed Terence Trent D'Arby's "Sign Your Name". The performance saw James land in the bottom three alongside Joelle Moses and Frances Wood, though his place in the semi-final was awarded by coach will.i.am. In the semi-final, James performed Queen's "Bohemian Rhapsody" – and was voted into the final by the public over fellow contestant Jaz Ellington; joining Bo Bruce, Leanne Mitchell and Vince Kidd from Team Danny, Team Tom and Team Jessie respectively. In the final, James performed three tracks: "I'll Be There" (The Jackson 5), "OMG" (Usher) with will.i.am and "Higher Love" (James Vincent McMorrow) for a second time. Alongside singer Bo Bruce, James was announced as the series' runner-up behind Leanne Mitchell.
