That song

Do you have a song that comes on randomly when you are out at a restaurant and it takes you back in time? Does it remind you of a lost love or special someone from your past that you never forgot?  This even came on during an anniversary dinner with my husband at the time. Needless to say, it distracted me from my anniversary and back to that mystery man from my past. I found myself reminiscing and wondering why I wasn’t married to him instead. This is that song for me.
