Nathan Green / Tom Waterhouse

I realised this one just before the Eels game last night.

Nathan is one of our awesome choir members at Hills.
Tom Waterhouse - if you don't know who this is, you either don't live in Australia, or don't own a TV.

Rob Beach / Skyfall Bad Guy

Nobody messes with Rob. STRENGTH AND HONOUR!!!

Rob Beach: Systems Emperor, Hillsong Church

The other guy.... I'll have to find out what his name is... for now we'll just call him Rob.

Chris Ross / Ryan Seacrest

This is probably the most obvious one ever... I can't believe Mel wasn't on board at first!

Chris Ross (aka THE ROSSATRON): Business Intelligence Expert at Hillsong Church
Ryan Secrest... you already know.

Joel A'Bell / Ryan Fitzgerald

Joel is the Lead Pastor of Hillsong Church Australia.
Ryan Fitzgerald is Fitzy from Nova's Fitzy and Wippa.

I reckon Joel has a good radio voice and could stand in if needed.
