Well, songs that include females' names in the title have always stood out to me because there just isn't a good song with my real first name in it. So, being a teenager in the 90's and loving the movie/soundtrack "Reality Bites", I listened to the song "My Sharona" alot and always thought "Hey, if my name was Sharona that song could be about me!". So, I started using that name for stuff.
Then, the song "Mellow Yellow" from the 60's (?) has a line in it "I'm just mad about Fontaine, Fontaine's mad about me...." and I have always liked that "groovy" song. So, I've thought about how cool and different it would be to be named Fontaine.
So, put them together and in my little world "Sharona Fontaine" is a groovy fly girl who is worthy of having songs written about her! Silly, I know, but I just wanted to have fun with it.
