I suspect son may be pretty serious about this drumming lark

He's just spent half an hour trying to nail the triplet fill into the bridge of Every Rose Has Its Thorn, then made me learn the guitar part so he can play it on the real kit, not the Guitar Hero kit - for another 15 mins :D

Video of the fill in question here - http://www.youtube.com/watch?v=c56vEgA4fjU#t=2m17s
