Security sales guy

We were invited to an open house recently at the new location for Downtown Jam.  I'm no singer, but my wife loves to sing so we went along and had a great time.  As we were leaving we asked if anyone wanted to share a cab home.  One guy said he was heading the same way so we got into a little small talk as we're waiting for the cab to arrive.  I had chatted with him earlier in the evening and complimented him on his singing, but didn't know much about him or how he knew our mutual friends.  As we're leaving, we touch on where we work - turns out he is the new sales rep at the small software company I left a couple of years ago.  Wouldn't think you'd find a great singer in the nerdy world of security software.
