For In Merry Measure, Hallmark Channel needed a tagline that playfully reflected a love story sparkling in the midst of a heated singing competition. In addition to the line chosen, here are some other favorites I came up with:

DO-RE-MI-FA-LA-LA IN LOVE

JOIN THE CHORUS. WIN CHRISTMAS.

THEIR VOICES ARE JOYFUL. THEIR HARMONY NEEDS A LITTLE WORK.
