The concert was supposed to start at 21:00 and end at 23:00, so at about 20:57 my friends started saying that the show will probably start at 22:00, because "all the bands" do this. Three minutes later, AC/DC started singing. I could have synchronised my watch by them. Also, at 23:00 they left the stage. The entire show was professional to the second, things worked almost perfectly, the coreography of their stage actions being totally in sync with the cameras, lights and other props.
I am not a great fan of the Aussie band, I like their music, but I only used to listen to their music when I was a child and I was falling asleep on Highway to Hell. Maybe that's why I thought that song and For Those About to Rock were the best of the songs and the rest weren't even close. But they were good enough.
I thought the vocal didn't quite have it in him, since after about an hour, the guitarist started a solo that lasted for 15 or 20 minutes. The energy in that man (Angus) puts me to shame and would have put me to shame even when I was a teen! While the audience was stuglling with the uncharacteristic cold weather and freezing wind, Angus Young was running around in his underwear, playing the guitar as he did so.
Here is a video from the event. Hav fun!
