I Looked at ver2 of this song and just noticed that it 
was a D major chord, instead of playing it like this:

|------------------------------------------------------
|----------7-------7----------7---------7-----------7--
|--------7-----------7----------7---------7-------7---7
|------7---------7----------7---------7---------7------
|---5---------4----------------------------------------
|------------------------7---------5---------3---------

||-----------5---3-------------| 
||---8-------------------------| 
||-----7-----------------------| 
||-7-----7---------------------| 
||-----------------------------| 
||-----------------------------| 

you could play it like this.

|----------2-------2----------2---------2-----------2--
|--------3-----------3----------3---------3-------3---3
|------2---------2---------2---------2---------2-------
|---0--------------------------------------------------
|-------------4----------2---------0-------------------
|--------------------------------------------3---------

||---3-------5---3-------------| 
||----2------------------------| 
||2----2-----------------------|
