When performed live, "Kung Fu" traditionally closed the band's sets in a two-minute rendition but was later moved to an earlier slot in the setlist.
On the Nu-Clear Sounds tour, it ran to around 5 minutes, with a DJ filling the song with martial arts and computer game noises.
The song appears on 1977, Intergalactic Sonic 7″s, Ash's first greatest hits collection, and the Tokyo Blitz DVD.
The second B-side, "Luther Ingo's Star Cruiser" was written by Wheeler and Mark Hamilton and is infamous for having uncommonly explicit lyrics.
It consists of the band playing the song in concert, and occasionally footage of different people performing martial arts moves are cut in to the video.
