Second time in a week for this one. Seán Dagher's (Assassin's Creed score &c) recent Shanty of the Week.

BTMP: A cappella renditions of songs sometime do not fall into strict meter.

'Fiddler on the capstan' is a tired old pop cliche. No lyrics required. Excepting, of course, one is compiling a book of shanty lyrics.

IIRC the the 'crew' on the capstan in the wiki image were paying passengers. The task is then already converted to a form of popular entertainment, at the very beginning of the 'classic' shanty era.

Every generation has its own brand of TikTok.
