"At the Hop" is a hit rock 'n' roll song written by Arthur Singer, John Medora and David White and originally released by Danny & the Juniors. The song was released in the fall of 1957, and reached number one on the US charts on January 6, 1958, thus becoming one of the top-selling singles of 1958. "At the Hop" also hit number one on the R&B Best Sellers list.
The song became more prominent after it was performed by rock and roll revival act Sha Na Na at the 1969 Woodstock Festival and featured in the 1973 coming-of-age teen drama American Graffiti. Musically, it's notable for combining two of the most popular formulas in 1950s rock'n'roll, the twelve-bar blues and the 50s progression.
