Macklemore isn't my thing, I don't mind the Killers, seems that entertainment is more for the tv audience than people at the ground. Personally I'd prefer a good and widely respected local rock act such as the Hoodoo Gurus, You Am I or perhaps The Celibate Rifles, (ok showing my age here)
I was at last year's grand final and it was the total vibe at the ground, the anticipation of a good game of football, a possible premiership win and good company of friends that had my attention, the entertainment seemed like a side show distraction.
