I was there last night, overall it was a great experience. There were 3 bands, The Meanies who were just ok, was a big wall of noise and they're more of a pub rock band than a stadium one. Said they're playing at The Tote next week and I can see them fitting in there. Amyl & The Sniffers were next who are also a pub band but they made it work and were fill of energy. Amyl is hot as *smile* and a great front chick. And finally the Foo Fighters who are a true stadium band and were awesome, played for 2.5 hours and kept the energy up all night. It was pissing down with rain for most of the night and I was drenched but it was a great show. It was my first time seeing them, I wouldn't call myself a huge fan over the years but besides one or two songs, I knew everything they've played. Probably wouldn't go see them again unless I got a free ticket but it was worth it for the experience and Dave Grohl is an absolute professional, worked the crowd beautifully. They're drummer (who's name escapes me) swapped with Dave for one song and they did "somebody to love" by Queen - Man can that bloke sing!
Edit - just reread your post Mr P and yeah Taylor Hawkins was really impressive.
