So many who died tragically too young...
But, I'd have to say the one that affected me the most was definitely John Bonham. I'd always been a fan of Led Zeppelin, but REALLY got heavily into them my freshman year of college, when I bought my first stereo. Much to my roommate's chagrin (who was into disco), I was constantly playing Led Zeppelin and Black Sabbath on the stereo we shared (my Marantz 1030 integrated amp and Infinity Qb speakers and his Technics turntable).
Tickets went on sale for the Chicago shows on September 25th. Back in the days before Ticketmaster, they were mail order only. I picked up a copy of the Chicago Tribune, to get the order form and was planning on stopping by the post office to pick up a money order later that afternoon. I learned of his death before I even made it to the post office. I was devastated. I was a drummer and Led Zeppelin was my favorite band. I was finally going to get to see them live, but it wasn't to be.
