By 1985 the band were playing regularly around Melbourne and soon released a 10-track demo composed of selections from their recordings followed by their début single, "Defecate on My Face" (1986), a 7" vinyl record packaged in a 12" sleeve with all four sides glued shut. This song is also found (but is unlisted) on the EP "Form and Meaning Reach Ultimate Communion" as a country version. Their next single, "40 Years – Then Death" (1987), was released on transparent vinyl in a clear plastic sleeve with no cover art or labels. This Is Serious Mum's first radio-friendly single, despite the obscure packaging, was received well.
