Aw, come on, OP. Why so grudging and sour? I’m hoping that, 20 years from now, you (and those likeminded in this thread) are at one of the biggest music festivals in the world rocking out to your current favorite bands. No, I really do, there’s no feeling like the festival feeling when a band you love is playing, no matter how old they get or how old the fans get, the live gig experience itself never gets old. I’ve been gigging for well over 30 years and I intend to keep doing so until they confine me to a high security nursing home.
I’m also hoping the younger people there 20 years from now are kinder and more tolerant of you continuing to enjoy the music and the atmosphere than you are of people my age doing same now. Hey I might even see you there, I’ll be the decrepit old dear in the 50 year old tour shirt head-banging feebly along to the beat.
