Harness your inner sober crazy Red and have a good time. I'd go if I were you.
Just steer clear of the morons, and enjoy the concert. The two older kids would be interesting to talk to, because they are younger.
You sound strong in your resolve Red. But as previous poster said, be aware of the smarts of the AV. It's conned me a few times.
You'll love it when you wake following day and you can remember everything. Creating a new history.
Have a great time Red.
