@Keba Si Rota:

That's really funny. I remember when I was starting out I tried to play "Rebel Rebel" by David Bowie and being just crushed that my rendition sounded nothing like the real thing. It probably didn't help that I didn't know how to tune my guitar back then...

I actually have played "I Wanna Be Sedated" on an acoustic guitar. I was a beginner, so the tempo was very sedate already. It was SO not punk rock.
