Query: Buy the straight stuff instead

I first heard Jonathan and Darlene (or Jo and Paul) in the early 1970s. My first take was: these people are brilliant! My second take: after five minutes, they are also close to unlistenable. For anyone with a decent ear, it quickly becomes painful hearing Jo barely missing the notes and Weston messing up the tempo. I guess it might be fun to play ONCE at a party, but I think a much better investment would be to buy any of the Jo Stafford reissues (there are excellent and cheap boxed sets available) and marvel at her superb musicianship. Listen to Stafford and you'll understand what being really "on pitch" is all about.
