Way after my 20s. I was right around 47, actually. I didn't gig as a teen. I played for a party once back then, not a booked/paying gig, just a casual arrangement for me to play and sing. And I hated the experience. My fellow teens treated me like I was a flesh-covered radio; I was just the white noise. I wasn't prepared for that. I was too insecure to perform music for people that showed no apparent interest, that gave no validation. So that was it. And then I married at 19, and my wife conceived our firstborn 6 months later. So we were kids having kids, and the idea of trying to make a go of it musically, or even being a weekend warrior, was out of the question. I never stopped playing guitar through the years; I just didn't gig. Fast forward to the year 2000, and the last of my three children got married. After she left home, I bought my first ever acoustic/electric guitar. I asked around and got a gig at a local coffee shop, and played through a borrowed amp (a Carvin AG100, IIRC). After that, for my birthday my kids and wife went in together on buying me a Crate TX30 "Taxi" amp, a Shure SM58 and a mic stand, and I was on my way. And I still don't like being treated like a flesh-covered radio, but I'm not quite as insecure as I was in my teens. I've just accepted that Americans typically listen to live music that way. Plus I get enough verbal affirmation and tip money to keep me going.
