I think I've posted this before - but what the hey. About 20 years ago, my friends Robin and Kathy were getting married. I sang it Kathy's wedding of course. I had had a joke with Robin for many years. When I would see him, I would say in my best WC Fields voice "Ah a robin, the first sing of spring!"
So at their wedding I sang "Now we see the sign of spring We see the Robin on the wing Let us all join hands and sing All for Kathy's wedding"
Neither one of them noticed.
