The Mighty Mighty Bosstones (informally referred to as The Bosstones) are an American ska-core band from Boston, Massachusetts, formed in 1983. Since the band's inception, lead vocalist Dicky Barrett, bassist Joe Gittleman, tenor saxophonist Tim "Johnny Vegas" Burton and dancer ("Bosstone") Ben Carr have remained constant members. The line-up also includes drummer Joe Sirois, saxophonist Kevin Lenear, guitarist Lawrence Katz and trombonist Chris Rhodes.

The Bosstones are often credited as one of the progenitors of the genre of ska punk and the creators of its subgenre ska-core a form of music which mixes elements of ska with punk rock and hardcore. Since the release of their 1989 debut Devil's Night Out, the band toured and recorded extensively throughout the 1990s, becoming a key figure in the development of the American third wave ska scene and one of the first bands to popularize the genre in the musical mainstream, reaching their commercial peak with their platinum-selling 1997 album Let's Face It and its hit single "The Impression That I Get". The band had released seven studio albums, three EPs and a live album by the time they announced a hiatus in December 2003. In 2007, the Bosstones reunited to resume recording and touring.

"He's Back (The Man Behind the Mask)" is a song by American shock rock musician Alice Cooper. It was released as the lead single from his 1986 album Constrictor, and the theme song of Friday the 13th Part VI: Jason Lives, a slasher film and sixth part of the Friday the 13th film series released in the same year. The song is heard various times throughout the film and in the end credits. Two other songs, "Teenage Frankenstein" (also from Constrictor) and "Hard Rock Summer" (which remained commercially unreleased until 1999) are also featured in the film.

The song features the famous "ki-ki-ki ma-ma-ma" (admittedly in its popular misheard version, "ch-ch-ch, ha-ha-ha") sound effect, a trademark of the Friday the 13th series.

"He's Back (The Man Behind the Mask)" was a minor chart success, popular among fans of Cooper's later work and enthusiasts of slasher films. It has been called "strangely new wave-ish" and said to "perfectly enscapulate the Friday the 13th films and the era in which they came to prominence."
