What was English rock band 10cc's third and last UK number one?

"Dreadlock Holiday" is a reggae song by 10cc. Written by Eric Stewart and Graham Gouldman, it was the lead single from the band's 1978 album, "Bloody Tourists".

It became the group's third and final number one hit in the UK Singles Chart, and final top 10 hit, spending a single week at the top in September 1978. The single also topped the charts in New Zealand, reached Number 2 in Ireland and Australia, and peaked at number 44 on the US Billboard Hot 100.

The song was based on real events Eric Stewart and Moody Blues vocalist Justin Hayward experienced in Barbados. Stewart changed the location to Jamaica. Graham Gouldman commented: "Some of the experiences that are mentioned are true, and some of them are ... fairly true!"

The beach scene in the official video was actually filmed on the Dorset coast near Charmouth. Golden Cap, the iconic hill and cliff of this region known as the "Jurassic Coast", is clearly visible for a few seconds in the video.
