At a warehouse, as Del Boy loads up the van with the latest item to flog called Kandy Dolls, Rodney tells him that he just joined a band that are styling themselves on Frankie Goes to Hollywood.
Del points out that Rodney does not have any drums and warns him that he should not be around "that bunch of wallies", especially their wild lead singer, "Mental" Mickey Maguire, who once bit another man's ear off.
Later, back at Nelson Mandela House, Del tells Albert that the Shamrock Club in Deptford, the "Paddies' Moulin Rouge", has no act for St. Patrick's Night since their resident band, the Dublin Bay Stormers, are in prison for their violent behaviour.
One evening, about a week later, as Del is talking to Monkey Harris on the telephone about the Kandy Dolls, he watches the TVs and discovers to his complete horror that the group, now named A Bunch of Wallies and having hired a new drummer, are at #26 on the UK Singles Chart and performing their song on Top of the Pops.
While that happens, Del quickly puts on his camel coat, while Albert exits his bedroom and tells him that Rodney is watching Top of the Pops on the portable TV.
