Mike Brady joined Triple M's Hot Breakfast on Thursday morning to belt out One Day In September, Live From Eddie's Desk.
He joined the show afterwards and farewelled the program with - of course - a bit of Up There Cazaly!
He really belted it out, as did Eddie, who got properly up and about for it, even singing by the end!
"GO THE PIES! GET 'EM! TEAR 'EM APART!"
It's absolutely brilliant!
