If you were wondering who the guy was that was singing the National Anthem Friday night, we have the answer for you.

He’s Bob Timney, aka Sgt Bob.

Sgt Bob has been a regular anthem performer at Pittsburgh sporting events for the last few years. He characteristically invites the fans to sing along with him during the anthem. As you can tell from all the open mouths in the GigaPizel shot from Friday night, the fans at Pegula responded appropriately.

Here he is in 2011 at the Penguins/Tampa Bay Lightning game.

and another from a Steeler game.

and, finally, the fans from Friday night.
