Humphries' one-man shows, which are typically two and a half hours long, alternate satirical monologues and musical numbers and consist of entirely original material, laced with ad-libbing, improvisation and audience participation segments. Humphries mostly performs solo, but he is occasionally joined on stage by supporting dancers and an accompanist during the musical numbers. Only one actor ever regularly shared the stage with Humphries, and this was during the Edna segments: English actress Emily Perry played Edna's long-suffering bridesmaid from New Zealand, Madge Allsop, whose character never spoke.
