I just did this real quick, not sure if it's accurate. Feel free to critique. Note that
of these are open strings, no barring unless you prefer it that way. It's really easy to
from the Esus2 to the Bmaj, and then just slide down to the Amaj. I wrote down in the 
that you can pick which you prefer to play the B or the Bmaj but note that the B chord
a full B, i didn't know what to call it.

Also, if you play the chords like I wrote them down there, it'll sound better and more
what I'm hearing when I tab it:

E   022100
A  002220
C#m 046600
