is it just me, or is the acoustic guitar really hard to play. escpecially while singing. Damn Thom Yorke. My friend who plays it well told me to use the simpler tab as opposed to the FULL tab. ie, this one http://www.ultimate-guitar.com/tabs/r/radiohead/paranoid_android_tab.htm

any other tips other than practice it slowly?
If you dont find theory interesting, then DONT study it. IF your TRULY serious about playing guitar(enjoying), then EVENTUALLY you WILL WANT to study it.
