Conversation with a friend reminded me of "The Piano Artistry of Jonathan Edwards," an album long forgotten. The Wikipedia article provides details and links.
Released in 1957, it featured Jo Stafford, then a popular singer, and her husband Paul Weston on piano, the two pretending to be Jonathan and Darlene Edwards.
A high-school friend of mine, Wylie Crawford, had it, and our family got a copy. Check out the album cover. There's a clue there.
There are two ways to enjoy their music. One is with people who who can recognize the difference between on-key and off-key, between on-temp and off-tempo. Every time they the Edwards go off, you'll groan in agony and then laugh. The other is with people who can't tell the difference. Every time the Edwards go off you'll groan in agony and then laugh and then your friends will look at you mystified and that will set you off again.
At least it did for us.
