I think everyone's done something like that at one time or another. I was once chatting with a guy at a social event and he happened to mention something related to his orchestra, can't remember the context any more but I assumed he played the clarinet in an informal group that met in a school hall every second Tuesday or something.
It was only later that I found out that it was the XYZ Symphony Orchestra and he was their music director/conductor of 25 or so years.
