Holy Heathens and the Old Green Man is an album by Waterson–Carthy. There is more instrumental accompaniment on this collection than on any previous Waterson–Carthy album. Tracks 13 and 16 could even be mistaken for the work of Brass Monkey. Despite the title, almost all the songs have a Christian flavour. "Diadem" has phrases which suggest that the figure being adored is some kind of "Green Man" rather than Christ. They have mostly avoided familiar carols, and even where the words as well-known, they have selected unfamiliar tunes. Running time 59 minutes 47 seconds. The album was recorded and released on the Topic Records label in 2006.
