It was 51 years ago today that Buddy Holly, Ritchie Valens, J.P. Richardson, and their pilot all died as the result of a plane crash in Iowa. It's remarkable that Holly was only 22 when he perished, and yet the cultural imprint he left is so significant. His music certainly influenced the Beatles in great measure. It's said that even the name "the Beatles" was in part a tribute to Holly's backing band, the Crickets.
Below are the Beatles' covers of "That'll Be the Day" and "Words of Love."
