One things for sure, I'm not going to miss the people abusing the Classic Rock tag.
Classical Rome is not 1400-1992.
Classic Rock does not en-tale the 90s.
actually, anything can be classic no matter how old, hence the term "instant classic"
it doesn't have to be "classic rock," the genre, to be classic. conversely, it also doesn't have to be classic to be in the "classic rock" genre.
It's not classic rock if it was written after the 18th Century.
it's not classic rock unless it was formed during the Precambrian Era
