Welcome to 24K Gold Music Shows! "Rockin' Robin" (originally released as "Rock-In Robin" on the Class Records 45 single) is a song written by Leon René under the pseudonym Jimmie Thomas, and recorded by Bobby Day in 1958. It was Day's biggest hit single, becoming a number two hit on the Billboard Hot 100, and spent one week at the top of the charts (number one hit) in R&B sales. 24K Gold covers this fun golden oldie.
