Secret Love - Doris Day
"Secret Love" is a great example of a retro, romantic song that borders on the sentimental. Sentiment is like a strong spice: A little makes all the other flavors stand out, too much and you've just ruined a meal.
You want people to listen to the music at your wedding and be touched and entertained. When they start rolling their eyes and everyone but great-aunt Elsie is whispering, "Oh, please," you've gone too far.
