Try using your favorite tunes for your family songs. If, for example, you are visiting Aunt Bonnie, who has a fat, fluffy cat named Delilah, you can borrow the melody from the song “A Christmas Tree Was Born in the Woods” with the words:
And Delilah the cat
Stripes are good
Flea beetles live in stripes.
Scratch it, scratch it!
Take any song and change the words however you want to make it your own song. You will probably find some of them funny and will become favorites in your family. Record the most successful ones on a tape recorder so as not to forget them.
