827. Bridge Over Troubled Water by Simon and Garfunkel (1970)

America entered the seventies much as it left the sixties...in turmoil. Simon and Garfunkel address the underlying tension and stresses of 1970 America in "Bridge Over Troubled Water." Interestingly, the song exposed turmoil within the duo. The pair split after the album, but they went out on top as the song proved a major hit.

There have been many covers of "Bridge Over Troubled Water" most notably Elvis in 1970 and Johnny Cash in 2002.
