Live sea shanties?

Ahoy! I'm in town for work and I'm curious if there's anywhere that does trad or sea shanties in the evening? My son is a few months old and I've been singing him Barrett's Privateers since he was born to get him to sleep, but I need to expand my repertoire. I suppose I could play Assassin's Creed IV, but I'd rather have fun with a bunch of others also into shanties.

Any suggestions are great, cheers!
