As with all Mason I'm familiar with, all strings are dropped one half step.  In
addition, drop the 6th string another step like drop D tuning.  You'll end up with
C#/G#/C#/F#/A#/D#.  Finally, capo on 2nd fret.

The D and E minor chords use all six strings, striking 6th string first as a base note
and then striking the higher note strings in a sort of down down up up down up pattern
where the first two down strikes are the base note.   When you play the E minor chord, 
add your index finger to the second fret of the 6th string to round it out since you're in
drop D.

I think there's also a little flourish of some sort on the D chords in the chorus, but I
can't figure out what it is.  Listen to the song and let me know if you get it.  This
is my first tab, so any feedback is appreciated.  All the best!

D
I met a man who was not quite an old man
Amaj7
Said he was an old boy
D
I would make a toast to believe and bet you
Amaj7
That I would be the same old man
D
Not the kind with a lost soul
Amaj7
Who can't put down his toys
D
Honey there'll be absolute peace in my heart
Amaj7
And resolution in my soul

Em		         A 	        D
So don't, don't, darlin' don't be surprised
Em	      A         D
When I don't leave your side
Em
'Cause there's not a single part of my love
     A		   D
That you should not believe
Em
I hope when I grow old
A		       D

D
I begged the pardon of the fullness of somebodies
Amaj7
Because I love the left lane
D
And I begged the pardon of the mass media
Amaj7
You know on Sundays I don't go to mass
D
And I tipped my hat to your dog in your yard by your
Amaj7
house, I'm waiting for a hurricane
D
To blow, blow, blow from the west to the east and tell me
Amaj7			D
who's gonna be here last
