Bobby Darin (born Walden Robert Cassotto; May 14, 1936 – December 20, 1973) was an American singer, songwriter, multi-instrumentalist, and actor in film and television. He performed jazz, pop, rock and roll, folk, swing, and country music.

He started his career as a songwriter for Connie Francis. He recorded his first million-selling single, "Splish Splash", in 1958. This was followed by "Dream Lover", "Mack the Knife", and "Beyond the Sea", which brought him worldwide fame. In 1962 he won a Golden Globe Award for his first film, "Come September", co-starring his first wife, Sandra Dee.

In 1962, Darin released "Mack the Knife", the standard from Kurt Weill's Threepenny Opera, was given a vamping jazz-pop interpretation. Although Darin was initially opposed to releasing it as a single, the song went to No. 1 on the charts for nine weeks, sold two million copies, and won the Grammy Award for Record of the Year in 1960. Darin was also voted the Grammy Award for Best New Artist that year, and "Mack The Knife" has since been honored with a Grammy Hall of Fame Award.
