The Green Island - Paddy Reilly & Jimmy Crowley

While watching the local university students stumbling around town wearing their “green” (which they’ll trade in tomorrow for green regurgitated beer) celebrating st paddy’s day, I thought of the color green and remembered this song. Lyrics are included. I’ve always puzzled over the meaning of the last verse. If anyone can help out I’d appreciate it.

“Is this a good time to remember
The brave men and women who died
Whose vision is misrepresented
By shadows who flicker and hide
They dish out their perks and their pensions,
While the big fella turns in his grave
To see the bright diamonds and jewels,
Cast down the cold crest of a wave.”
