This episode includes Neil Innes as a George Formbyesque version of Tom Baker's Doctor Who in blackface, one of multiple instances of Innes using blackface in the series. This is something of a surprising inclusion, as when the Bonzo Dog Doo-Dah Band dressed in blackface during [Episode #1.3 (1968)], Innes was the only one who did not join in.
The end of the episode sees Roy Plomley sending up his role as creator and presenter of the long-running radio programme "Desert Island Discs", complete with use of the theme tune. The programme asks guests to imagine what records they'd take with them if they were stranded on a desert island - Plomley sails to an island to take back some overdue records and books.
