It's Daddy Cool - lead singer Ross Wilson (also been in another group in the '80's - Mondo Rock).

When we go to watch the West Coast Eagles (AFL), this is played after the game. In a stadium with around 40 000 people, it's something to behold - lots of grooving wiggling bodies, all singing along.

Looks like they're hitting the road again, with The Beach Boys, no less....
