Top 5, in chronological order:
-8/7/03: Hearing Someday I'll Be Satruday Night at my first Jovi show/first concert ever, and being amazed the feeling of seeing a band do a song that means the world to me live. Started my concert obsession.

-10/28/07: Livin' In Sin, Right Side Of Wrong, Lay Your Hands On Me. My fourth Jovi show, and first time I ever got real rarities. LIS and LYHOMwere major treats for me as a major NJ fan, especially as both were uber-rare at the time. Neither beats RSOW though, as it's my absolute favorite song off Bounce, and I thought I had no shot of hearing it after the Bounce Tour.

-7/12/08: I wasn't expecting anything great setlist-wise out of the free CP show, but I ended up getting 2 songs I'd never heard before. Blaze was a nice treat in the main set, but the real highlight was Always to kick of the encore. I was actually whispering to myself during the encore break "Please play it Tico, Please play it Tico", and nearly lost my mind when the drums started.

-7/14/08: Dry County at MSG Night One. I had been texting with a couple of people from the board, and they kept telling me to expect a major surprise (a photo of the setlist had leaked) but I never expected it to be DC. Until this year, it was the absolute highlight of my Bon Jovi fandom.

-2/25/11: This year's MSG Night 2 was shaping up to be a bit of a disappointment. Yes, the show had been good, and the encore had started with my fourth Dry County, but it was still lacking something. Then after Prayer, Jon sent the guys back to their spots for a second encore. Always was nice, but it was the next song that easily tops everything else in my Bon Jovi fandom. Earlier that night I had thrown together a makeshift banner that said "I've Waited 17 Shows For These Days" and held it up during WGIGO (had pretty close behind the stage seats). Jon definitely did see it, whether it had any bearing on what happened next I don't know, but after Always the band started These Days, and I finally got to hear my absolute favorite song. I was shaking the whole time, barely believing what I was hearing. Amazing moment. In These Arms and Just Older to end the night were nice as well, but TBH I barely remember them in the post-TD euphoria.
