A Light Moment

Thanks to all those that participated in the first Who Am I? ® game.
Many people got that one right, and as a prize for getting the correct answer.

Allow me to sing to you in person the next time I see you.

Now here we have the 2nd installment of the popular game.

_______________________________

I play netball and I play footie. But haven’t played footie in a long time (coz of job commitments) but have been around to support the Sirens. I’m funny and I like to tease people. When I play footie I’m usually put as right defense. Nowadays I usually use another part of myself to good footie use. My voice. People say they can hear me a hundred miles away. In reality it’s more like 200 miles. I have a cousin who’s also blessed with good vocals.

Who am I?
