The version of "Electricity" used is the same as the one featured on their debut album (which itself is the band reworking Martin Hannett's original Factory version). The band was originally going to use their very first version of this song, but found the drumming to be inferior and so settled for the remix of the track instead. "Messages" is the more popular 10" single version; "Tesla Girls" is a compilation version not previously released; and "Talking Loud and Clear" is the 7" edited version.
