Given that PSB have been a fanbase-only act with little to no mainstream exposure for over a decade now, I can't say that I see any recent PSB releases as embarrassing. No one sees or hears any of it aside from us, so what's to be embarrassed of?
Now back in the day when I was ultra concerned with PSB's mainstream fortunes, that's another story.
New York City Boy is probably the one that jumps out the most to me. It's not that I hated it, ok maybe I did, but I was also embarrassed by it and the video as well. I remember Neil being a guest on Loveline and going into and out of commercials they played short clips of the New York city boy video! I was cringing with embarrassment that their first American media exposure in nearly a decade was this!! LOL
The only other that jumps out at me is Absolutely fabulous, the song and the video. That was probably more embarrassing than New York city boy but since it never got a release of any kind in the US, I never had to fear that anyone would hear it.
