They used to play the video for Kick Down The walls on "Toronto Rocks" a lot in the mid-1980s. Most of my friends hated the song and theband but I liked them, thought it was ok, but the singer seemed out of breath. A studio version of the song might have been better than that live one.
I liked them as they were similar to other bands I liked back then, Kiss, Twisted Sister, MotelyCrue.
It wasn't until I started downloading/ looking at youtube a few years ago, after I upgraded from dial-up service, that I got to hear more Wrathchild UK. Good stuff
