Tommy James named his hit song MONY MONY because he saw an insurance billboard across from his apartment, Mutual Of New York

I had the track done before I had a title. I wanted something catchy like "Sloopy" or "Bony Maroney," but everything sounded so stupid. So Ritchie Cordell and I were writing it in New York City, and we were about to throw in the towel when I went out onto the terrace, looked up and saw the Mutual of New York building (which has its initials illuminated in red at its top).
