Osher Günsberg and Jackie O appear in this episode in a Sydney studio that was made up to look like the stage in Melbourne, and Urzila Carlson appears in this episode via a laptop link from her quarantine hotel room in New Zealand. All three had spent time in self-isolation in Melbourne, which allowed Osher and Jackie to be exempted from quarantine by New South Wales authorities, but didn't prevent Urzula from being quarantined for two weeks on her return to New Zealand.
Production of this episode was scheduled to take place on 22 August 2020, but was suspended after a dancer stated, less than two hours before filming was scheduled to start, that they had tested positive to COVID-19, and seven other crew members linked to the show also returned positive results, leading to the host, guessing panel, celebrities and production staff all being placed in self-isolation. Production of Who Wants to Be a Millionaire: Hot Seat (2009), which is also filmed at Docklands Studios Melbourne, was also suspended as a result of the cases because it shared some facilities with The Masked Singer despite it being filmed at a different studio on the Docklands lot. The episode was filmed on 8 September 2020.
In an interview given by Jackie O on her program on Sydney radio station KIIS 106.5 the morning after the episode's filming, she said that if she had stayed in Melbourne for its filming, she would have had to have spent another two weeks in quarantine on her return to Sydney. This implied that she and Osher Günsberg were only given exemptions from quarantine by New South Wales authorities because they returned to Sydney, both due to other commitments - Jackie to her radio show and Osher to The Bachelorette Australia (2015) - as soon as they had completed their two weeks of self-isolation in Melbourne.
