of the song is slightly different.

then you need 2 guitars, if you play along with the song,
just choose one, they both sound good.

Chorus 2x, I think the second time they hit every chord just 4 times,
instead of 8, but I'm not sure

Tip: if you have a gibson or gibson-type guitar (epiphone) with the large
switch for the 2 elements and don't have any pedals to switch the distortion,
just put the rhythm-volume on 2 and the treble volume on 10, then put you
amplifier on half distortion. You can use the rhythm for the verses and
treble for the chorus and the hard part of the last verse. have fun.
