The House of the Rising Sun
The Animals version is a classic rock staple. Nina Simone actually made the song even dirtier than The Animals. Dolly Parton's weird 80s version is surprisingly fun. Woody Guthrie delivers that early folk sound which fits the song so well. The Ventures take the sound the Animals did and make a killer instrumental of it.
Bridge Over Troubled Water
Simon and Garfunkel, Aretha, Elvis, Cash, Roberta Flack, Willie Nelson and even The Jackson 5 deliver unique and distinct versions. The song is so good almost anyone can make something special of it.
Eleanor Rigby
Beatles, Joan Baez, Aretha again, Ray Charles version is incredible, Oscar Peterson has a nice little jazz number with the theme. I am not sure about the Jackie Wilson version but it's a little funky. It's hard to make that song not work. Booker T, Richie Havens too.
