When Scottish postman Nathan Evans is not delivering parcels, he is posting viral videos on TikTok.

The Royal Mail worker has emerged as the source of a worldwide trend on the video sharing app.

But instead of dance videos, life hacks and make-up tutorials, the 26-year-old from Airdrie in North Lanarkshire has become "TikTok famous" for singing ancient sea shanties.

Since December, Nathan has racked up millions of views for his sailor songs and he is responsible for what is being called "Sea Shanty TikTok".

The centuries-old songs were traditionally sung by sea farers around the work, but after a few requests to Nathan's social media accounts and other landlubbers duetting, the craze grew.

Fans have even taken to Twitter to declare 2021 the year of the sea shanty.

Nathan told the BBC Radio 4's Today programme: "It is crazy and has gone much further than I ever thought it would go.

"I did a sea shanty back in July 2020, just because someone had asked in a comment under one of my videos.

"So I uploaded that and it reached 1.1m views. I thought there must have been a demand.

"People were looking forward to more and they were commenting underneath every video after that saying can you sing this one, can you sing that one – it was just requests from people for me to sing them."

After his first video "Leave her Johnny", he posted another called "The Scotsman" which has gained 2.8m views and then his biggest video to date "The Wellerman" which was posted in December and has has been watched 4.3m times.

It has also been duetted countless time and been turned into a collaboration with other TikTokers.
