Here's something to think about..something that I've brought up to friends a few times in recent years.
Right now, there aren't too many bands that have lost all of their original line-up. (I can think of maybe 2)
It's only a matter of time, and not much now, that there will be no more 'living members' of many classic rock bands....Led Zeppelin, The Doors, The Beatles, Rolling Stones, The Who, Pink Floyd, Queen, etc..
The good news is, we can still enjoy the music when they're gone.
