The version I remember was the title track on an album ("All Bells in Paradise") released in the late 1960s by the Valley Folk (one of whose 4 members was Steve Heap, who now runs Mrs Casey Music, and Sidmouth and Towersey Festivals). In addition to the verses given on the thread Joe has just linked to above, I think there was one (after the "river" verse on the lines of "At the bed's foot there lies a hound
Drinking the blood as it daily runs down"
