Written in 1974, and released as a 21:00-minute track on Yes' "Relayer" album. This magnum opus piece of music contains all that Prog Rock critics dislike about PR. It's too long, it's too complicated, the message is unclear, there isn't a toe-tapping hook, and the group is being too pretentious to think that anyone would want to sit through such a thing. My reply would be that, if anyone can compose, write, play and perform like this ... why wouldn't they?
TGoD is one of Yes' signature compositions, and this slightly shortened version, enhanced with the European Festival Orchestra, is a showcase work by one of the top PR groups of all time. I hope you enjoy this song about humanity's predilection for conflict, and the always regrettable outcomes:
"Stand and fight we do consider,
Reminded of an inner pact between us,
That's seen as we go,
And ride there,
To fields in debts of honour defending."
"Stand the marchers soaring talons,
Peaceful lives will not deliver freedom,
Fighting we know,
The point to reaction,
As leaders look to you attacking."
