**how can a tune be about the waterways**

Easily. There are 2 examples on our new album.
A Dead Bod: Songs of the Humber Waterways.

'Sobriety on the Humber' is a melodic interpretation of.....well, you can read the notes on the website. It involves Chris Sherburn skippering a Humber keel in a force 8 with passengers on board. By Bill Sowerby, it's also an absolutely cracking tune played on mandolin and whistle.

'The Flying Lock key' is also a melodic interpretation of an outing on a narrow boat. I think you can guess what it depicts. By Dave Hill, it is also a great tune played by Dave on accordeon.
