Men of Harlech is a song and military march which describes events during the seven year long siege of Harlech Castle between 1461 and 1468. Commanded by Constable Dafydd ap Ieuan, the garrison held out in what is the longest known siege in the history of the British Isles.

The music was first published without words in 1794 as Gorhoffedd Gwŷr Harlech (March of the Men of Harlech) in the second edition of The Musical and Poetical Relicks of the Welsh Bards, but it is said to be a much earlier folk air.

Men of Harlech occupies an important place in Welsh national culture and gained international recognition when it was featured prominently in the 1964 film Zulu.

This new arrangement comes from the pen of Welshman Gareth Wood. It cleverly fuses the tune to more exotic rhythms associated with Latin America and the Caribbean.
