The songs about Anthony Bennett played at the start, interval, and end of the show are both from the album Surf Music by New Zealand musician/comedian Paul Williams, now perhaps best known as the Taskmaster's Assistant on Taskmaster NZ (2020). James Acaster was a contestant on Taskmaster (2015).
James' jacket and shoes (avengers themed Vans) were first worn on Taskmaster. He decided on wearing the jacket for this special as he liked it so much and said he'd feel disappointed only wearing it once.
