Striving for best on ground tonight are singer/songwriter Mike Brady, comedian Frank Woodley, singer Rebecca Barnard, and musical comedian Tim Minchin. Mike, Myf and Frank contest the mark with admirable air-guitar action in Know Your Product, and bluegrass band Hard Drive yee-haa up a storm in Look What They've Done To My Song Ma. Mike reports on the endurance of "Up There Cazaly", Frank is tackled on an issue of crowd participation, while Tim and Adam play on in a touching and possibly out-of-bounds musical playout.
