And from The Guardian 28 October 2021 Nadia Khomami Arts and culture correspondent;

Alongside the piece by Kelly, which was performed at the Theatre Drury Lane at the time, there is also a completely unknown score written by William Douglas, 4th Duke of Queensberry, a landowner and society figure whose gambling overshadowed his musical skills, until now.

There is music for a sea shanty tribute to Nelson, whose lyrics have been known about since a letter from Nelson to William Douglas was sold at auction in 2013. It’s now clear the duke had added music and a chorus to words transcribed by Nelson after he heard his crew chant the song in the aftermath of victory at Cape St Vincent in 1797.
