Jman, Rise Up Singing gives them as:

Em - - - /Cmaj7 - - - / Am D G C / G C Am B7 /

The 'Girls in white dresses' verse uses

E - - - / A - - - /

as the first two lines, and

'When the dog bites...' uses

Em - Am B7 / Em C - - / - - A - / G C Am D G /

Each slash indicates a line. A dash indicates the previous chord repeated. Not all these chords seem to fit the song as I remember it (a common failing with RUS), but I didn't take the time to work it out. I'm sure you can probably work it out for yourself with this beginning.
