The introduction to the song has also occasionally also been used for banter or to sing covers or parodies of songs. In the early 1990s, Page and Robertson would often talk about the intro's "hot guitar lick". An example of the intro being used to sing another song is found on the "Rock Spectacle" version, in which they sing an excerpt of their own song "Grade 9." The aforementioned "River Music Hall" version begins with a parody of Kenny Rogers' "The Gambler".
