Guess the Whistled Tune

See if your friends can name the Christian tune you're whistling, and vice versa. Perhaps see how many Christian tunes you can whistle and have the others guess within a minute. Alternatively, whistle only 5 seconds of songs and see if others can guess what they are? Do you think your Guardian angel is a good whistler? In fact, they can play along and guess your whistled songs too - only you'll have to wait until heaven to hear how well they scored.
