Hi Jesse,
No, Barclay James Harvest is a British band. They were very popular in Europe but not so much in the U.S.
They are known as "the poor man's Moody Blues"

I am not sure why other than the MB'S were a big influence and many of their songs reflect that. They even have a song with that title, Poor Mans Moody Blues and it's a spin off of "Nights in White Satin".
I love a lot of their music...it's really good and I believe they still do concerts. I think they have split up and some of the original band members are with their own bands now but they still tour once in a while.
Anyway, it's old hippie music so I thought you might like it....lol
I bet Yuri has an album or two of BJH
