Crews from three Scottish Coastal Rowing clubs, Boatie Blest, Newhaven and Portobello this week dressed up in old fashioned clothes, assembled on the beach at Porty and sang the traditional dreg songs as recorded and noted in the 1930s by US folklorist James Madison Carpenter.

The result was captured by BBC radio programme-makers – you can hear it here, for as long as the BBC keeps it online. The relevant segment starts at 1:18:45, and in it US folklorist Bob Walser explains how the songs work.

Bob found the songs while studying Carpenter's material, and it was originally his dream that they should be sung in their proper setting by authentic voices.
