Erm.. Normally on the chorus I would play C#, A, D.. I think.. You seemed to miss out the middle chord. I might not have the chords right, but you definitely missed one out..

You play it differently to how I would play it as well, especially the intro. I don't hammer on..

Also the last line of the chorus should go C# A D B..

It's been a while since I played it though :p
