Hey I was wondering where I can find guitar tabs for Happy Birhtday. But I don't want the easy boring version, I want the rock/heavy metal version like this http://www.youtube.com/watch?v=n5EXIoJCVP0
- The reason that I want to learn it, is because I want to surprise my sister when she's going to turn 18 this month :D So it'll be nice if you could send me a link ;)

Here's something I found

That gives you the power chords & the classic way. If you want to spice it up a bit, play it with the electric guitar like Samo did, and maybe incorporate your whammy bar in some parts (if you have one). :D
