Here's what I think the chords in the song are played. The whole song has the the following pattern except the end: e|--------7-7-7---------5-5-5---------5-5-5---------5-5-5-| B|-3-3-3---------3-3-3--3-3-3--3-3-3--3-3-3--3-3-3--3-3-3-| G|-0-0-0--7-7-7--0-0-0--2-2-2--0-0-0--2-2-2--0-0-0--2-2-2-| D|-0-0-0--7-7-7--0-0-0---------0-0-0---------0-0-0--------| A|-2-2-2---------2-2-2---------2-2-2---------2-2-2--------| E|-3-3-3---------3-3-3---------3-3-3---------3-3-3--------| There are also some mute picking which anyone can easily guess by listening the song. above chord pattern is repeated in the whole song. The ending is something like this: e|--------7-7-7---------9-9-9-9---------10-10-10-10---------12-12-12-12-| B|-3-3-3---------3-3-3-----------3-3-3---------------3-3-3--------------| G|-0-0-0--7-7-7--0-0-0--7-7-7-7--0-0-0---7--7--7--7--0-0-0---7--7--7--7-| D|-0-0-0--7-7-7--0-0-0--7-7-7-7--0-0-0---7--7--7--7--0-0-0---7--7--7--7-| A|-2-2-2---------2-2-2-----------2-2-2---------------2-2-2--------------| E|-3-3-3---------3-3-3-----------3-3-3---------------3-3-3--------------| The above pattern is repeated a few times which can check from the song and also extra don't mean that the interval between the strum and the next strum is more. It is just to the note look better as part of that single strum.
