While most of the songs are single versions, "E=MC²", "Medicine Show", "Sightsee M.C!" and "Just Play Music!" are included in their exact album mixes. In the cases of "Rush" and "The Bottom Line" this had the effect of condensing the songs into simpler pop song structures. "The Bottom Line" for example in its single edit did not feature the introductory 'Horses are on the track' section. The edit of "Rush" was not the UK edit (that was featured as the b-side to The Clash's "Should I Stay or Should I Go") which faded out briefly before the end of the original album version. The edit featured removes the entire 'Rhythm and Melody' breakdown.
The version of "Harrow Road" here is a mix that is not available anywhere else. Most fans refer to it as the Ska Mix.
