"Come On" (often called "Let the Good Times Roll") is a song written by New Orleans rhythm and blues artist Earl King. He first recorded the song as "Darling Honey Angel Child" in 1960 for the Ace Records subsidiary Rex. Later that year, he recorded it as a two-part song for Imperial Records using some new lyrics. Retitled "Come On", it was released in 1960 with "Come On - Part I” as the A-side backed with “Come On - Part II” (Imperial 5713).

The song's lyrics are based on "Let the Good Times Roll", the 1946 jump blues hit by Louis Jordan and his Tympany Five. However, instrumentally, it is a showcase for guitar playing. Music writer John Perry compares it to Freddie King instrumentals, such as "Hide Away" and "The Stumble". He adds that it is performed in the "guitar-friendly key of E ... specifically designed to cram as many hot licks as possible into a single number".

"Come On" did not appear in Billboard magazine's R&B record chart, but gained a higher profile due to Jimi Hendrix. The song was one of the earliest songs played by Hendrix, starting with high school bands at the Spanish Castle music club south of Seattle. In 1968, he recorded "Come On - Part One" with the Jimi Hendrix Experience for their third album, Electric Ladyland. Hendrix follows King's rhythm guitar parts, but performs the song at a faster tempo, giving the song a more rock feel. Bassist Noel Redding and drummer Mitch Mitchell also provide a more driving rhythm, which adds emphasis during Hendrix's guitar solo. It was the last song recorded for Electric Ladyland. According to Redding, "that was done to fill out the album ... We just played it live and they took it".
