My all-time favorite cover: The Leningrad Cowboys and the Red Army Chorus, Knockin' On Heaven's Doorhttps://www.youtube.com/watch?v=CV6ETVQgob0
"R-E-S-P-E-C-T" is original to Otis Redding, not Aretha Franklin. And he wasn't referring to being polite, either.
Big Mama Thornton recorded the original "Ball and Chain", later covered by Janis Joplin, and "Hound Dog", covered by Elvis.
I wish I were kidding when I say Celine Dion covered "You Shook Me All Night Long"
Madonna and "American Pie"
Korn, "Another Brick In The Wall"
