Each year, a national UK radio station dedicated to playing "classical" music, runs a public vote for its "Hall of Fame". I believe voting takes place in January and February, and they then broadcast the top 300 over Easter.
In their context, "classical music" takes quite a wide definition. They play what most people would regard as "classical" - ie symphonic works by Beethoven and the like, and operatic arias, even gregorian chants, etc, but they also add modern film scores, and modern so-called "popular classics" by individual vocalists (in the Catherine Jenkins mould) and musicians (Claire Jones, André Rieu) etc: quite a mixed bag of the good, the bad and the ugly!
I wonder if it might be fun to see if, by the power of MM's collecting voting power, we are able to sneak a JN track into their top 300! I'd suggest that when the voting begins (and I'll advise, with a link) we each vote for 2 choices of anything we fancy, and all include a vote (preferably a #1 choice) for a JN song agreed beforehand.
As for what that song should be ... I think to reduce the chances of disqualification, a simple hard-and-voice song would be more likely to slip through. Most of MEM would thus qualify, but with uninitiated listeners often taking exception to her early voice (not me, I hasten to add), maybe one of the HOOM songs would work best. Off the top of my head, here are three suggestions:
Esme
On a Good Day
Ribbon Bows
(Probably the BEST choices of all would be Three Little Babes - which is of the required antiquity, but does not seem especially popular among MM-ers ['cept me], and Ca The Yowes To The Knowes which scores highly on every criterion except that it's never been officially released).
