This picture was taken on the 16th April 2003 at John's home in Thomastown, county Kilkenny by local photographer Dylan Vaughan.
He took at least twelve pictures. This one was used on the cover of Heaven And Earth.
Gizmo the dog however was added afterwards from a separate picture taken the same day.

The space John is photographed in, is called the Hen Run.
