Pat is mostly know as the house guitarist A Prairie Home Companion and most of his song combine witty jokes with wide gourmet of country, blues and folk guitar licks. This song is very different, being a strangely non-moralizing gospel tinged ditty. It only looks like a religious song from the outside, in the same way it only seems like there is some physical altercation going on in the first verse.
In fact, the first verse is saying: we were having discussions and big disagreements about major issues, but it was fun because we could do it in friendship. In the end, we are on this road together. For me, as an atheist, it means ‘death’, the end, nothingness, but for people with a more religious background, this may mean ‘heaven’, the ultimate goal, all. We may differ in what we expect to find behind the Door, but that we are united on our road towards that Door. There is also a bit of Heidegger’s Sein zum Tode.
I will not go deeper into analyzing the lyrics – people don’t understand why you can write a 25 page paper on one poem. I still think there is no better tribute to any poem than demonstrating it takes pages and pages to do what the poet does in a few line.
But here are the chords. If you like this stuff you should also check my post on Blind Connie Williams.
I have transcribed the basic chords, which are dead easy. The diminished chords used as transitions, often to the A are explained by Pat himself in this video.
