Sea Shanties is an album by Ian Giles, Spiers and Boden and Graham Metcalfe.
Most of the tracks are sung as an unaccompanied quartet of male voices. The sound is so thick that there is probably only one microphone. There are two instrumental tracks. This appears to be the first ever recording of the tune "Ashley's Flag", printed about 1800. The album was available at UK tourist centres rather than high street music stores. Recorded and released in 2002.
