I used to be able to play the piano / keyboard pretty well, but it's been YEARS since I've even tried so I doubt I'd even remember how to "read" the music sheets now lol.
I used to be able to play the drums too, not briliantly but okay-ish.
Ohh, and who can forget "Smoke on the Water" by Deep Purple on the guitar? My mate taught it me within 10 minutes lol
I think that song is the first song everyone learns to play on a guitar / bass.
