"Bad Boy" is a song by rock and roll singer Marty Wilde, released as a single in November 1959.

[3][4] Announcing the release of the single in Disc, producer Jack Good wrote that "It's Been Nice", written by Doc Pomus and Mort Shuman, was the "top side".

[1] Promoting the single several weeks later, it was described as a "double-sided smash… Bad Boy coupled with It's Been Nice".

[5] Mort Shuman had intended to give "It's Been Nice" to Elvis Presley, but instead gave it to Wilde after the two struck up an instant friendship.

[7] Reviewed in Melody Maker, "Bad Boy" was described as "easy going, with a folk-sounding air about it".
