To play devil's advocate, let me ask this - why should people stop and listen to another version of songs that many have heard literally all their lives? It's not like most people are going to hear "Night & Day" and say, "WOW! There's one I've been waiting to hear for the last 5 years!"
Then again, if you played something they'd never heard before, I doubt the reaction would be any different. It might even be worse!
I've been saying here for the last few weeks or so that the culture has changed irrevocably in terms of the role that all music plays for "most people". It's become entirely more functional now than it was just a few years ago, and that function has changed from social dancing/listening to "mobile lifestyle accessory/soundtrack". I'll not be convinced othersise.
Whether or not "we" like it or think it's a "good" think is not the point. The point is that, yes, things have changed, and no, they aren't changing back anytime soon, if ever. Myself, I'm ok with that, even if it's rendering me in my current mode obsolete (whether or not I can/want to explore new avenues in music or be content to ride out the horse I've gotten this far on no matter where it leads - or doesn't - is something I've been giving some pretty serious thought to lately). Times change, and people's sense of "time" and "place" have been evolving since the advent of all the digital/portable technology for the last few decades. It's finally reached the "point of no return", and that's just how shit goes, dig? It's our fortune to be alive during what might be referred to by some as a "paradigm shift". Lucky us!
I hope I don't have to say that none of the above is construed as a dis to the old types music or the people who still enjoy playing them. It's not, and I'm one of those who still does both ("freebop", my primary expressive medium of choice, is almost 50 years old now, so any thought that it's still "new" and/or "challenging" is so much bullshit). All I'm saying is that if we continue to play this music out of love, then we're doing it for the only reason that will continue to have any real relevancy, and that's going to be to ourselves. Good enough. But if we do it and seriously expect to make a connection to "the public" at any level beyond that of "charming curiosity" and/or the occasional true "music lover", hey - forget about it. Ain't gonna happen.
And yes, all of the above holds true, imo, to all kinds of live music, although more current idioms might garner more of an immediately attentive short-term audience. Again - people's notions of time and place have changed once and for all, and with them the "role" that they want/need for music to play. C'est la'vie.
