Yes, I was just listening to Hats (1989) and I wanted to see if the band members had done anything else since then. I've been listening to A Walk Across the Rooftops a few times in the last few weeks, since I first got it in the summer.
I think the Blue Nile is basically broken up. Their 3rd and 4th albums, Peace at Last and High, didn't garner the same level of critical and popular recognition, so maybe it's best to leave it at that (from the sound of Moore's last interviews about the band, it seems to be a bitter ending, at least on his part).
