There's a handful of songs that fit in this group, or into a list of songs that I've always liked, but I think are often overlooked.
Back in NYC is one that I overlooked for a long time, but it's become one of the highlights for me. And Hairless Heart is, I think, really fantastic. And then someone earlier mentioned The Lamia. I think with all three of them, it took the first box set, and that live version of them, for me to really latch on. I was so used to live versions of In The Cage (3SL was what finally got me into the band), that the rest of the album didn't really resonate. But once I heard live versions of each of those; man, I love them. The Lamia in particular is a great live track. And I get it; I know that the second half of the Lamb isn't as respected at the first half. And I know that it comes to a "conclusion" somewhat abruptly. But I really like the second half.
Many Too Many is one that it took a while for me to find; one of my least favorite of their albums, so it wasn't in regular rotation. But I've grown to really love that track. Like it or Not is another late cut from an album that I think is really strong. I think either of them would have made a great addition to the '07 or '21 tours, but I knew there was no way.
Other folks have mentioned Keep it Dark, and I echo their sentiments. Great track!
It's Gonna Get Better is one that I've known for ages, but never really card about. My buddy and I wore out his copy of The Mama Tour on VHS. But we never paid much attention to this one, because we knew that the Cage Medley was coming up, and that's what we were waiting for. But it's a really great song. And especially the last couple years, I have to keep reminding myself that, indeed, It's Gonna Get Better (at least I hope so).
The last I'll mention is Anything She does. When I was younger, I hated that song, I think mostly because I liked the radio hits, and wanted to hear The Brazilian. I also never understood Benny Hill, so that song was never in the rotation. And then I started to really get into the older stuff, and I poo-pooed IT as a whole; I was too cool for that radio-friendly crap! Foxtrot or Die, man! (Ahh, the arrogance of a teenager) But at some point, something with it clicked with me, and I really like it. I love the addition of the harpsichord-ish sound in the last verse after the break. It's nothing more than a silly little pop song. But I think it's a great silly little pop song.
