Looking for a song (help!)?

I was told that a, few years ago in the early 2000's, my father (C. dewayne gregory), recorded a country song with a woman named Lisa. I think her name was lisa plummer or porter. It was a song about leaving, or about a secret romance. I would love to find this song, because it was the first song my father ever wrote, but it was so long ago I cant remember the name or how the song went. If you think you might know the song, give me the title and or the album. Thank you
