Ok, I was listening the Gerry O' Beirne's song "Shades of Gloria" that Maura O'Connell sings so well. There are a few things in the song that I'm having trouble understanding. First, what does "Shades of Gloria" exaclty mean? And also there is a line about "Micho in his prime." Who is Micho?

Here are the lyrics:

I am going to the country, going down that verdant lane
With nothing but a whistle in my hand and a pocketful of rain
Can you hear that distant sound coming down the West Clare Railway?
Running with the shades of gloria

The wind is full of memories that murmur and sigh
Hills lie in the foaming grass of Clare below the cold moon's eye
But you should come and see them now when they are on fire
And running with the shades of gloria

And the waves roll at the headland when the tide is rising there
And here there is starlight falling down on the hills of Clare
I knew them when I was hungry and I knew them when I was scared
And running with the shades of gloria

And I am going to the country where Micho in his prime
Weaves a thread of melody in his own sweet time
You can hear him sing and whistle anytime you care
To go running with the shades of gloria.

I am going to the country going down that verdant lane
With nothing but a whistle in my hand and a pocketful of rain
Can you hear that distant sound coming down the West Clare Railway?
Running with the shades of gloria
