Jonathan and Darlene Edwards were a musical comedy double act developed by American conductor and arranger Paul Weston, and his wife, singer Jo Stafford...Weston first assumed the role of a bad lounge pianist in the mid-1950s, as a way of entertaining guests at Hollywood parties, but was urged to record an album of songs in the unconventional style after giving an impromptu performance in 1956...Weston asked his wife to join the project. Stafford, a classically trained singer with the ability to sing both in and out of tune, readily agreed, and named her character Darlene Edwards. -- Wikipedia
