I always do, including where they are from, or some little bit of info. One guy is retired Navy, I usually mention that, gets applause every time. When we were traveling some, Id occasionally make up a location where someone was born. My brother and I were actually born in Kansas City, which sounded cooler than Anderson, IN, so I'd say that. Once though, I said that one guy was from Weehauken, New Jersey, just becaause I thought it sounded like fun. Sure enough, at this little town fair in Indiana, a feella came up and said he was from, you guessed it, and started talking to the band member about Weehauken...oopsie... I faded away to the dressing room and left him on his own ;-)
