If you thought 2020 was an odd year, leave it to the first few weeks of 2021 to bring the “sea shanty” sing-along trend on social media video-sharing app, TikTok.

Lately, users have banded together to sing sea shanties, work songs once commonly sung to accompany labor on merchant sailing vessels.

Sound weird?

Not to the Northeast Ohio Regional Sewer District, who decided to hop on the TikTok trend, with employees singing their own version of a popular sea shanty, with more than 1,000 views on their Twitter.
