2. singing and playing drums (i know you said it does not appeal, but you are rhythm wizard so i just wondered if you are good at it)
i am usually not interested in singing lead while playing drums, only backups. but i think what generally happens the first time, for example, is you will sing something on beat 1 and accidentally hit the snare on beat 1 (when you weren't supposed to). and then you go 'oh crap i can't believe that just happened' and then you never do it again. that's the main thing to watch out for
