It's mainly guitars, basses, ukuleles and they sneak in the odd banjo because they know I don't like them lol. I know some people that run local jam nights but I really don't enjoy playing in public. I always think it's a great idea until I start playing and then wish I could disappear. But it's always nice to meet and chat with others that love music. Has your son been playing long? Music is such a great thing for them to learn. I tried to teach my boy when he was younger but he just complained that his fingers hurt.
