The CNN coverage of the death of troubled singer Amy Winehouse noted a sad connection among some of rock's most tragic icons.
Winehouse was 27 when she died ... the same age as Jimi Hendrix, Janis Joplin, Jim Morrison, Kurt Cobain and original Rolling Stone Brian Jones. There's even a book on the subject: "The 27s: The Greatest Myth of Rock and Roll." (Amazon shows it as out of print, but I wouldn't be surprised if Winehouse's death led to an updated version.)
I guess it's not really as strange a coincidence as it sounds -- it's not uncommon for rock stars to hit it big in their early to mid 20s. So it's not surprising that those who are subject to the tragic combination of sudden fame, sudden wealth, substance abuse and pressure to top themselves would fall victim just a few years later.
