So I researched a bit and I found a forum where somebody said they spoken to somebody that knows a bit of Cumbrain. According to them "Gar tuht river" could! mean "Go to the river". Also I found that "rheged" was an of celtic kingdom. So the lyrics could! mean something like this "Go to the river, get to rheged".
