Ghost. I was not a fan of theirs at all. I loved their look, but could not get into their music. Then I went to an Iron Maiden concert and Ghost was opening for them. By the second song I was hooked. I have been a huge Ghost fan since. My wife and I are going to Vegas to see them for our anniversary this year.
I was at Hersey Park for a company picnic one year and there were a lot of people walking around dressed up as Weird Al. While waiting the group from my store on a ride, I noticed there was an amphitheater behind me. I turned around and leaned on the rail trying to figure out what was going on when someone dressed as Weird Al came up next to me and started looking down at the stage, he asked if I knew what was going on. I shrugged and then he ran down the steps and onto stage. It was actually Weird Al.
