Aye, Matey: The Corsairs and "Leaving of Liverpool"

Pirate lovers - or lovers of old sea shanties - today's your day! Our random tune is from a group that's a bit of a mystery. I remember seeing The Corsairs at some festival in San Antonio years ago and purchased their album. This is not the 60s doo wop group, but an American a cappella group that sings sea shanties and pirate songs. I can't find too much on them except that they've released a number of albums, each named after a color - for example, The Red One, The Black One, etc. This song, Leaving of Liverpool, is from their 1998 first album The Red One.
