"Dreadlock Holiday" became the group's international number 1 hit topping the charts in the
UK, Belgium, New Zealand and The Netherlands. The single also reached number 2 in Ireland and Australia, became a top 10 hit in Norway and Switzerland and top 20 in Germany and Sweden. In Austria the song was 10cc's sole entry in the charts, peaking at number 18. In North America, "Dreadlock Holiday" became a minor hit, peaking at number 45 in Canada's
RPM charts and number 44 on the US
Billboard Hot 100. When asked why he thought the song did not do better in the US, Gouldman said that reportedly some radio stations would not play reggae of any kind. In the UK, the song was the band's third number 1 and at the same time final top 10 hit. In a 2025 interview, Gouldman responded to claims that the song's lyrics perpetuated stereotypes about the
Caribbean by stating that while people from the region he had encountered had expressed uniformly positive opinions, he would not have written some of the lines in the present day. ==Charts==
