Bell X1 - 74 Swans chords

One of my favourites from Bloodless Coup and a downright nice song.

It's the same chord progression repeated for each verse. Any comments/corrections welcome.

Standard Tuning

            Bb                    F
You counted 74 swans on the canal
            Bb                    F
You counted 74 swans on the canal
              Dm
And you were glad it was an even number
   C 
Everybody had another
    Bb                        F
No-one was facing this cold alone
      Dm
Cold alone
       C
Cold alone
       F
Cold alone

They were gathered between bridges 
in the steely sunshine
Bookend by ice on either side
Here comes a pair on final approach
Wings like great white bellows
Gathering inward to land
and it looks like grace

You counted 74 swans on the canal
You counted 74 swans on the canal
And you were glad it was an even number 
Everybody had another
No-one was facing this cold alone

I thought you were right there with me, 
on my left side
Too eager to get where I'm going, 
I left you behind
But you were on the last watch, 
The passing of the torch
You counted 74 swans, now there's 75
