And yes, it will indeed be a sad day when those esteemed people do finally pass on.
One day, even Status Quo may stop touring, and then what? Who is there to create that similar level of excitement when they announce they will headline Glastonbury or emerge from the studio with a new album.
Who is there working at this time who has a large enough catalogue and the sort of mass public appeal that is required for such a lofty position as "Keeper Of The Rock Flame".
Now, from my exceedingly myopic viewpoint, I suggest the following, and have difficulty coming up with many more contenders.
The Elder Statesman of 1970s Vintage:
The young (?) upstarts from Punk/New Wave to early 1980s:
From the 1980s, and seemingly never to escape that connection:
From the 1990s to now(ish):
Damon Albarn / Blur
Manic Street Preachers
Mumford and Sons (love 'em or loathe 'em, I think they will be around for a while yet)
Creators of two of the best Albums of 2013, but will they still be doing the job in 2033?:
Cynically, it appears that the music business has gone backwards 60 years to a time of a single controlling force (for Larry Parnes in the 1950s, read Simon Cowell in the 21st Century), and the defined career path of From New Kids On The Block to Old Geezers Standing On A Stage is seemingly not currently an option.
We are now in 2013 and in need of the next Elvis or Beatles moment - that point in time where something comes along and completely changes the business model, and hopefully for the better.
But never mind - the sun is shining and all is (seemingly) well in the world (unless you live in Egypt).
Here's an exceedingly summery tune, provided by one of the bands who could've made the list (but they seemed to have disappeared up there own fundament)
Noah And The Whale - 5 Years Time
