“Beat It” by Michael Jackson (1982)
Everyone knows that MJ was a genius-level singer, songwriter and dancer. But this early acapella version of the Thriller cut shows that he had some pretty mean beat-boxing skills, too!
“Veronica” by Elvis Costello (1989)
Maybe stretching the definition of a “classic”, but this cut from Elvis Costello has always been one of our all-time favorites. It gets serious bonus points for being co-written with none other than Paul McCartney! The final version features the Beatle on bass, but this spirited demo is just Elvis double tracked with himself.
