Was just reminded of Dave Brady (Obit; Guardian) and Swan Arcade http://en.wikipedia.org/wiki/Swan_Arcade .

Reinhard Zierke's site has discography and track listings,

http://www.informatik.uni-hamburg.de/~zierke/folk/records/swanarcade.html

YouTube has a few to sample:-

Swan Arcade - Down In The Valley To Pray
Swan Arcade - Babylon Is Fallen

Favourite Swan Arcade album? Any with "Peat Bog Soldiers" on; unfortunately no YouTube for that, short clips available on commercial sites.

Occasional shanty groups excepted (eg Stormalong John, Sail Pattern), nobody seems to do this sort of rowdy, raucous, harmony singing nowadays. Glorious to hear, and great to take part in. (Please, [Please!] correct me if you think I'm wrong.
