This song was written by the famous songwriters couple Felice and Boudleaux Bryant who for example also wrote "Love Hurts". The first version of the song was by the Osborne Brothers in 1967, but many others have recorded the song like Lynn Anderson and Dolly Parton. I like this version the most!
The song appears on the second album of Dillard & Clark, "Through the morning through the night". D&C are formed by Doug Dillard of the Dillards and Gene Clark of the Byrds.They were backed up by, among others, Bernie Leadon, Chris Hillman, Sneaky Pete Kleinow, Byron Berline and Michael Clarke.
The lead vocals are by Donna Washburn who is Doug Dillard's girlfriend at that time. She was also the background vocalist for Leonard Cohen and Joe Cocker. I wish I could have found a better picture of her.
