We have a small, informal chorus at work that I sing with when my schedule permits. Today they had a SummerFest and asked us to sing. We did a 20-minute program of patriotic favorites, ending w/ all four verses of the Star-Spangled Banner. (Take a look and you'll see why verses 2 thru 4 are almost never done - doggerel!) We were crammed onto a stage barely big enough for us all to stand, and it had a canopy low enough that folks standing more than a few yards away probably couldn't hear much, but it was fun.
