Well, 6 songs from the album all got played at least once at various points during the LH tour, with songs from the album being played a total of 48 times, making it the 3rd least played studio album (with 7800 and Bounce lower than it).

(Source for the above, as ever, is bonjovi-archives.com)

I think it is partly because it wasn't a big hit in the US that the band practically disowns it (especially at US shows), but I think I recall Jon also saying that the songs are a bit of a downer, and in general he want the Bon Jovi live experience to have more of a party atmoshpere.

Go figure
