I don't for one second think "I'm Your Man" is a cover. Jon has put ONE song on a regular Bon Jovi album that he didn't write or co-write and that was a contractual obligation. Also, Leonard Cohen isn't the only one who ever wrote a song with that title. Wham had a hit called "I'm Your Man" (yes, I'm sure most of us would like to forget it, but it WAS huge) and Barry Manilow has a song with that title. Josh Turner had a country hit that was huge with the very similarly titled "Your Man." It's really a rather generic phrase--there's no reason at all to think that Jon can't write a completely different song with that title.
