TIA, I was well into this band in the early '80's. Check out the "Earthshaker", "Black Tiger" & "Meanstreak" albums. "I Believe In You" is on "Earthshaker" (the best album) and "WOC" on "Black Tiger". Whether they're available on the same CD?....not sure. There is a Best Of lurking somewhere. I lost track of them when they went more poppy/ AOR after the above triumvirate, but that doesn't mean they weren't any good! Their 1st album actually came out in 1976 I think ("Yesterday and Today"), and their 2nd ("Struck Down") in '78 - both of which were good, but I had to flog due to financial deprivation. Aaargh - I wish I still had them!!
