It's a matter of taste whether you like that Lou Gramm style of singing or not. It has its place in AOR or melodic rock.
I'll give Constantine credit that he can probably sing in principle. But he was mostly flat on that song, nerves, bad in ear monitoring, uncomfortable with the initial sparse arrangement which gave him comparatively little to latch onto, whatever. Or just a sheer bad key day. It happens to the best singers. But he wasn't quavering around much, but rather pretty solidly flat which indicates that he can at least hold a note. I've heard good singers off key throughout a whole concert, but always by the same tonal difference as if they had bee set to the wrong autotune.
The Righteous Brothers version is, of course, impeccable.
You can AORize it pretty decently too though (Deep Purple connection coincidental!):
http://www.youtube.com/watch?v=1Gibiy4QsG8&feature=relatedWith his hairdo and voice, Constantine should maybe apply with Foreigner. He's certainly got the curls. Even if the current Lou Gramm replacement Kelly Hansen does a very good job (and is a genuinely nice guy).

something nice about Foreigner. 30 years after I would constantly deride them and even leave a gig of theirs early for boredom.
And an American Idol candidate I've never even heard of before. And to boot, posted a clip with scenes from Demi's and Patrick's (RIP) ultimate
tear jerker Ghost. I'm getting real old.
