The album represented a significant change in The Clash's musical style, which now featured major elements of ska, funk, pop, soul, jazz, rockabilly and reggae far more prominently than in their previous two albums.[1]
On the original version of the album, "Train in Vain" was not listed on the sleeve, nor the label on the record itself, but a sticker indicating the track was affixed to the outer cellophane wrapper. It was also scratched into the vinyl in the run-off area on the fourth side of the album. Later editions included the song in the track listing.
