This has been driving me crazy for awhile. I was in the grocery store and this song came on the radio. It sounded like Cornelius Brothers & Sister Rose with a harmonica at the beginning and throughout the song. The lyrics I wrote down were, "I'm falling or fallen in love but I'm so afraid". "You're the best things I've ever found". It's not Oh Girl by the Chi-Lites either. It was almost an upbeat melody. Any guesses?
