Some people are great entertainers....and Jason Mraz is one of those people. He entertained the Halloween crowd for almost two hours. This was the first time I had seen Jason in concert. My girlfriend has seen him a couple times and said he was really good. She also has a copy of his live cd "Sold Out", which I listened to several times. The guy is funny and the Halloween show was no exception. Among his original tunes he threw in a few covers. "Mary Jane" was one, there was another that was a few songs into the set that could have been an Earth, Wind & Fire song, but I'm not sure. My only "complaint" would be that he didn't play much of his earlier music. I own two of his albums and would like to have heard a couple more tunes from "Waiting for my rocket to come in." I think he only played two songs from this album. "Tonight, not again" is probably my favorite song on that album and it wasn't one he played. Maybe next time. The bottom line is you're all but guaranteed to leave a Jason Mraz concert feeling good. If you don't then you've got some issues to work out.
