Christina Aguilera... I know, you're probably thinking "What is MJ doing at a Christina Aguilera gig?". Well the truth is, I'm in Vegas, she's in Vegas and, well I got a ticket for cheap, so why the hell not! Off I headed to Zappos Theater , knowing no one and unsure of what to expect. Obviously I know all her big hits, anyone who listens to the radio does, but I wouldn't class myself as a fan. I was, as I've said elsewhere, out of my comfort zone at this gig! I needn't have worried though. She came onstage a little after 9:00 PM and played for 2 hours. OK, she wasn't on stage for the full 2 hours as there were a few short breaks for costume changes, but that's only me being picky. All the hits were played and, yeah, I may have sang along to some of them. There were a few songs I didn't know, but the crowd did and they belted them out with her. Mind you, she didn't need the help, her voice is just stunning, as powerful as it
