“I’m Knee Deep in Loving You” was written by the Nashville songwriter Sonny Throckmorton. Roy Drusky first recorded it in 1974, and the song was taken up by several country and bluegrass acts.
The song is a happy declaration of being deep in love. The image of the title — knee deep, and sinking happily further — describes a singer who has fallen past the point of pulling back and would not want to.
The song’s warm, easygoing feel suited bluegrass.
