In July 2014, when David Arnold performed his debut live orchestral concert, at London's Royal Festival Hall, McAlmont appeared as this former collaborator's surprise guest vocalist – "my secret weapon," said Arnold – for the songs, "Surrender" and "Play Dead".
In 2014 and 2015, McAlmont teamed again with Bernard Butler to perform live at various venues, including the Lauren Laverne radio show. In 2016, McAlmont sang on the album Call Me Lucky by Alex Webb (musician) & The Copasetics; he has subsequently collaborated with Webb on a words-and-music show based on the music of Billie Holiday. In 2019 McAlmont again collaborated with Webb to publish a new album titled The Last Bohemians.
