The Conan performance was bad, there are better live clips on Youtube already from various shows that put that one to shame. I think people expected too much initially...and ithey are over hyped a bit. Live gigs like Conan always sound bad, and subdued regardless of the band.
I am not disappointed with the album, there are some good songs that will grow on you as you listen to them. But I was not expecting it to be very good, so from my perspective I was pleasantly surprised.

Joe is still great, and there is some serious guitar playing on the album.
Overall I would give a 7. Try to get past the released tunes on MySapce and listen to some of the other lesser know known ones. Whatever you do don`t let a live performance on TV be the reason you don`t give the album a full listen. Cause I think live performances like that always sound horrible (did I mention that already LOL).
Learning to Fall, although a ballad is decent tune. My Kinda Girl is another good one. I love the vibe on Sexy Little Thing. That tune they played on Conan was probably the worst possible choice they could have made with no hope of ever being able to reproduce that gang style backing vocal live, which just made the song sound thin and lifleless. Ala Def Leppard......cough.........lol
But some of the other live vids on youtube make me still want to catch a life performance. Don`t analyze......listen. It is good old, fun times rock and roll album....nothing more and nothing less. If it is your thing you will like it, if not you won`t. Life changing.....Uh....no. But not bad.....not as bad as some people are going on about. There are always skeptics, and not everyone will like everything, hence the choice to not buy it. It doesn`t suck, it just may not be your cup of tea.
I still have to add........kudos to Sammy for still looking and sounding as good as he does at his age. Man the guy is my Dad`s age and can still kick it! If you were not a fan of Hagar, I doubt you will be now, but nobody can deny is staying power.
