According to the info at YouTube:
From Patsy's album "Chip Chip", 1974. The background singers on this album are the famous "Jordanaires".
Patsy Sledd was a very underrated artist and it's quite hard to find information about her on the Internet. I've read that she toured the Caribbean and Vietnam as a back up singer for Roy Acuff. She have also been a back up singer for Tammy Wynette and George Jones. She was friends with Barbara Mandrell and made several outfits for Barbara. She released several singles and two albums: "Chip Chip" and "Your's sincerely".
