Is there an age limit?
The Stones don't have one!!
I'm younger , 70 next birthday, played all my life, small time gigged most of it, and still gigging with 2 full bands and one acoustic trio. I'm preferring the acoustic trio more these days, - less gear, less hype, easier on the ears bla bla, but I'm still leading the two other bands with lead guitar & vocals. But when we're setting up in front of folk half my age , I've got to wonder what they think this old white haired guy is going to achieve?? - if they hang around they're always happy with some good Clapton/Knopfler/ZZtop etc tunes being knocked out. But I can't help thinking , maybe the acoustic is the easy way to slide out of the scene. Acoustic to me is playing the same tunes but with an electro-acoustic & percussion, ......same old tunes played at less volume & without a strat/SG or valve amp.
I do live & play in the South of France for last 15 years where the scene is different in a very nice way, more relaxed, often outdoors, ...any other folk asking the same question?
