Thought I'd add the lyrics for this charming song by the late Alasdair Clayre. I think I have most of it down for the first 4 verses (maybe some uncertainty in a couple of insignificant words) but as you can see, I have some uncertainty in the final verse. Any takers?

You can hear the song here.

Thanks!

A Gentle Easy-Flowing River by Alasdair Clayre

When you come afloat in the morning light
And you're towing through the summer weather
You use no clock but the ebb and flood tide
It's a gentle easy-flowing river

But when you're out on deck in the big spring gales
And you hunch aboard your barge and shiver
You go creeping slow against the weight of water
With the ebb tide pushing down the river

And it's cold on board in the winter dark
And you think the night'll last forever
And you crouch and wait below in your cabin
Till the dawn tide takes you down the river

And you're stood out there in the lightning storms
When the big waves thump the boats together
And the thunder shakes the steel below you
And you're working on the open river

Well it ebbs and floods with its rain (and oil?)
When London's gone it'll flow on forever
With the sea and the grime in its black salt water?
It's a gentle easy-flowing river
