Ok, I listened to the track, felt even more in the dark (sounds a bit like an earlier, younger, boy-choir Sting??). I checked out the Wikipedia to investigate.
IT TURNS out the guy is English, well here's one of the first issues. Americans are
generally ignorant about music from the UK, and if there's no top 40 hit that stays on the chart for 6 or more weeks the band tends to fall by the wayside. The highest position he got in the US was 17, by the way, which in and of itself makes me feel like he was just not that popular there (where I grew up).
The second issue is that his last hit was in 1986, which is some years before I was born. Sooooo unless my mom loved this guy (as she so loved U2, Sting, Led Zeppelin, etc), chances are I would just never have come across him.
I have heard of Yes, but I couldn't recall any specific song. Sorry TH! Thanks for the enlightenment, but not my taste.
