Second the motion on Stan Hugill's recordings. Go to www.stanhugill.com. If you can find it, his recording of "Shanties From The Seven Seas" is a rare gem, recently transferred to CD.
I'd take SINSULL'S advice, too. Radriano just showed me some songs from The Boarding Party's recent release onto CD, a recording from the vault. Great, unusual stuff! A must-have!
