Correction. The album was "Straight from the Tunnel's Mouth". I found a tape backup of it. Sorry, I didn't take a note of artist or label on the tape. However the track list is as follows;

Waterways Lament
Poor Old 'Orse
The 'Orrible Trip
Tommy Note
Boaty Boaty Spit in the Cut
Lass of Coventry
Single Bolinder
Girl on the Cut
Winson Green Jail
Dudley Tunnel
