Who are the greatest rock and pop groups of all time, if we restrict ourselves to those groups whose members are all still alive today?
If duos count, then we can include the Everly Brothers, Simon & Garfunkel, and Ike & Tina Turner.
All four founding members of the Kinks are still kicking.
We've also got Cream, who famously reunited for four 2005 shows in London.
Sly & the Family Stone were a large group, but Wikipedia seems to think all of their original lineup are still alive.
All four of Crosby, Stills, Nash & Young are still with us.
Whatever you may think of Michael Jackson's strange personal life, or his brothers' lack of successful solo careers, all of the Jackson Five continue to live and breathe.
Fleetwood Mac had several different lineups over the years, but I don't think any of the members are underground.
Of course, the nearer we get to the present, it becomes easier to name bands who haven't had a member die, but harder to agree on who the most "classic" or "biggest" acts are. But a few more who qualify are Black Sabbath, Aerosmith, Talking Heads, Blondie, ABBA, the Police, ZZ Top, Van Halen, U2, and R.E.M.
