Maybe it is just my life long exposure to loud cars (and engines of all types), shooting without hearing protection, and turning the stereo up loud enough nobody can hear me sing, but with my volume settings I didn't notice anything.
Enjoyed the show, and outside of getting used to a new personality it was great. I have met MS in the past at ranges, so it wasn't a total shock to see or hear him. The thing I noticed most but am not sure what it is is that MJ looked different. I never figured it out, but it will probably be something like glasses or shaving and I will go Doh!
