I play out in a couple of bands still and I don't see that stopping any time soon. The keyboard player in one of them is in her 50s and she's also in other bands as well. Playing music is one of the areas of my life that I just won't let atrophy.
Like my buddy Mike always says "If you don't play out, you don't play" I suspect Anthony started to feel the same way. I'm always happy to see people pick music back up in any capacity.
