I didn't notice any issues with security. I was 10 rows back directly in front of his piano. The security I thought was fantastic where I was sitting. I do know that the security for these events is usually hired out by a larger company with the venue only providing basic security.
As for the crowd, they didn't ruin the show or distract me. It was just a note about the level of energy. Sorry to hear some had trouble with security.
And well said Mike
