Which two singers recorded "Ebony and Ivory"?

Less than two months after the single dropped, Eddie Murphy and Joe Piscopo were on SNL tearing it apart. Murphy played Stevie Wonder, and Piscopo played Frank Sinatra, kicking Paul McCartney off the record. Piscopo's Sinatra called the black keys and white keys metaphor "too artsy for the public" and offered some blunter (and much more offensive) alternative lyrics. The SNL writers' room wasn't the only place that didn't like the song, and over the years, it's been voted one of the worst songs ever recorded. At least we came together on something.
