What famous Christmas song made its debut in Holiday Inn?

"White Christmas" first appeared in Holiday Inn before becoming one of the biggest hits in holiday history. This wasn't the original intent, though - the song was almost an afterthought. However, once it was clear it was going to be a modern classic, they made another movie based on the song 12 years later called White Christmas!
