Been playing bass for 5 years now in a metal band.
Also play some guitar/drum/keyboard for fun.

Not sure if thats sarcasm or not, all it really takes is practice. i often did backup vocals for a band i was in during high school, but when we played live i would sing/play drums at the same time obviously.
i'm sure there are plenty of musicians who can drum/sing.
