Oh, I would have loved to hear that!
I've done the very same thing. I also tend to sing along in the grocery store if there's no one else in my aisle... and okay, a little dancing with my cart, too.
My father did it bigtime
once: he was a pilot (among other things) for the Army, and when he was flying alone, he often passed the time by singing. One of his favorite songs was "Sink The Bismarck
," a rousing Johnny Horton tune about tracking the WWII German ship Bismarck
:"...We'll find that German battleship
That's makin' such a fuss
We've got to sink the Bismarck
The world depends on us
So hit the decks a runnin', boys
And spin those guns around
And when we find the Bismarck
We've got to cut her down..."
Well, one day when we were living in Germany (around 1960), Papa was belting out that song as he circled back in toward the post, and when he finished the final verse, he radioed the tower to request clearance to land -- only to find that his radio had been open the whole time, and the GERMAN
traffic controller had been listening!
"Did you ever find ze Bismarck, Captain?" the controller asked in a heavy German accent.
"Ah, no sir, not today," my father said sheepishly. "I think I'm about fifteen years too late."
There was a chuckle over the radio and then, "You are cleared for landing, Captain. I hope you will visit us in ze tower and give us a zerenade."
It was an awfully nice invitation, considering he'd just been singing quite enthusiastically about the destruction of a German battleship! But my father was so embarrassed he didn't go.
