The Wellerman (Sea Shantey) concertina alone (6 v)

Performed and recorded by Dr. Stephen Duncan
Concertina (which would be appropriate for this period of time)

"Soon May the Wellerman Come", also known as "Wellerman" or "The Wellerman", is a folk song in ballad style first published in New Zealand in the 1970s. The song refers to the "wellermen", pointing to supply ships owned by the Weller brothers, who were amongst the earliest European settlers of Otago.

In early 2021, a cover by Scottish song artist Nathan Evans became a viral hit on the social media site TikTok, leading to a "social media craze" around sea shanties and maritime songs.

New Zealand–based music teacher and folk music compiler Neil Colquhoun claimed to have collected the song around 1966 from one F. R. Woods. Woods, who was in his 80s at the time, had allegedly heard the song, as well as the song "John Smith A.B.", from his uncle. The song "John Smith A.B." was printed in a 1904 issue of The Bulletin, where it was attributed to one D.H. Rogers. David Hunter Rogers was a first-generation Scottish immigrant who worked in the Union Company beginning in 1880; Wellerman does not resemble "John Smith A.B." or his other published poems.
