The first chord, which occurs throughout the verses, is A7/B , though he actually walks the bass line (with hammer-ons) from E to F# to A to B. If you're simplifying the chords, I think a Bm or a Bsus2 sounds more accurate than just playing the A7. The right bass note is critical to the sound. A7/B x-2-2-0-2-x [Intro] A7/B [Verse 1] A7/B Carrying your ashes from bar to bar D I'm in a mess and you're in a mason jar A7/B With you under my arm like a football D I'm not ready to let go and that is all G You were never big on conversation A7 And that hasn't changed since your cremation [Chorus] D G And I feel most times like you do D G You know I feel most times like you do D I wish that I was hard nosed Bm7 Fight a forest fire with a garden hose E7 And be brave enough right now N.C. A7/B To start on something new [Verse 2] A7/B You were right there in the urn Light as a feather D If my hands weren't shaky I'd Glue you back together A7/B This watering hole was our favourite stop D So I'll take off the lid and pour a drink down the top for you G And I'll pull down on that magic lever that A7 Makes it stay the past forever [Chorus] D G And I feel most times like you do D G You know I feel most times like you do D Someone stabbed my voodoo doll Bm7 Now it hurts each time that nature calls E7 N.C. A7/B And you're lucky that nature's finished calling out to you [Verse 3] A7/B You were down to your very last Little belt loop but you were D Tougher than a pit bull in the paratroops A7/B And if you're afraid of getting hurt You suffer more ills D Like the hypochondriac who dies choking on his pills G So I should swallow real hard and deal with this pain A 'Cause I'm as wasted as a neat freak in a hurricane [Chorus] D G And I feel most times like you do D G You know I feel most times like you do D I thought I was the one that died Bm7 This was heaven's weird amusement ride E7 But you pinched me in a dream A And I saw it wasn't true [Outro] G A D F#m So I'm dumping your ashes on the floor G A And we'll laugh as people slip on you D F#m While coming in this door G A And I'll drink on what you said D F#m To stop my feet dragging N.C. No one dog's bark should ever stop the waggin'
