WASHINGTON — South Carolina native Chubby Checker’s 1960s dance hit “The Twist” will join Simon and Garfunkel’s song “The Sound of Silence,” which was written amid the turmoil following President John F. Kennedy’s assassination, as two of 25 recordings selected for preservation at the Library of Congress.

These are just a few sounds of the 20th century being added to the National Recording Registry for long-term preservation due to their cultural, artistic and historic importance.

The library said Checker’s rendition of “The Twist” became a symbol for the energy and excitement of the early ’60s after “American Bandstand” host Dick Clark chose Checker, a native of Andrews, to record a new version of the song.

Later, the 1966 album “Sounds of Silence” by Paul Simon and Art Garfunkel was a hit in its day but not before the duo struggled and split early on. Their song “The Sound of Silence” from the aftermath of President Kennedy’s assassination 50 years ago this year had initially flopped, but it became a hit after it was re-edited as a single. That prompted the duo to reunite and record another album under a similar title.

Garfunkel, 71, told The Associated Press he’s thrilled and flattered to have his work preserved in the Library of Congress. He said the hit album was a life changer for him and Simon.

“When you look at the little mesh, wire microphone ... and you address people on the other side of the mic, you hope that your performance will be special, and you hope that it will have lasting power,” he said.

Their words and their tune have taken on special significance in American culture. Hearing Simon sing “The Sound of Silence” on the 10th anniversary of the 9/11 attacks, NBC newsman Tom Brokaw briefly struggled for composure. The music, he said, evokes memories.

This is the kind of impact the library was looking to preserve, “to celebrate the richness and variety of our audio heritage,” said Librarian of Congress James Billington in announcing the selections.

The recording that received the highest number of public nominations for this year’s registry was Pink Floyd’s “The Dark Side of the Moon.”

Other selections included the original 1949 cast album for “South Pacific” and the soundtrack to the 1977 movie “Saturday Night Fever,” featuring the Bee Gees.

Recordings by Will Rogers, Jimmie Davis and President Dwight D. Eisenhower capture part of the political climate of their eras.
