The Dreadnoughts - Avalon

I lie in centuries grove
Where the cool wind blows
Where the cool wind blows
Upon this stone plateau
Where the cool wind blows
Where the cool wind blows

A dust is falling in the air
The murderers are millionaires
I will wait to see you there
Avalon
Avalon

A young man fell below
Where flowers grow
Row on row
A madman lays the foe
Where flowers grow
And the children know
Bullets shatter naked bone
A little girl grows up alone
Carves your name into the stones
Of Avalon
Avalon

You are my peace of mind
Where the river winds
Where the water shines
Orchards hills and vines
Where the water shines
Where the water shines

You don't belong to anyone
When the day is said and done
You'll receive your native son
Avalon
Avalon

Avalon is a mythical island in the Arthurian legend (meaning "the isle of apple trees") that was later used to name a variety of British colonies as they sprung up around the globe in Canada, America, Australia, and New Zealand.

The Dreadnoughts are a folk-punk band from Vancouver and this song seems to be about a murder or massacre - but I cannot narrow it down any further. Any leads?

The lyrics remind me of

I have no more information on this song. I have also posted one of their songs previously.

I was listening to some of their songs and kept coming back to this one.
