Samuel Roy Hagar (born October 13, 1947), also known as The Red Rocker, is an American rock vocalist, guitarist, songwriter, musician and entrepreneur.
 Hagar came to prominence in the 1970s with the hard rock band Montrose.
 He afterwards launched a successful solo career, scoring an enduring hit in 1984 with "I Can't Drive 55".
 He enjoyed huge commercial success when he replaced David Lee Roth as the lead singer of Van Halen in 1985, but left the band in 1996.
 He returned to the band for a 2-year reunion from 2003 to 2005.

Sammy Hagar is Sammy Hagar's second solo album, released in 1977.
 It is also often referred to as The Red Album, as it includes Hagar's first anthem, "Red", which is also the basis for his nickname "The Red Rocker".
 Future multi-platinum selling producer Scott Mathews was talked into playing a drum solo on "Red" after being told Ringo Starr had played his only drum solo in the very same room on The Beatles' last album, named after the EMI Studios this album was recorded in, Abbey Road.
Red Voodoo is a Sammy Hagar and The Waboritas album.
 When Hagar finished touring in support of his "Marching To Mars" album, he recorded this record.
 "Red Voodoo" is really an extension of the party atmosphere that permeated Hagar's concerts on that tour and this album has that whimsical party vibe.
 "Mas Tequila" was the lead single and it almost served as a commercial for Hagar's other career endeavor, as his Cabo Wabo tequila was being distributed throughout the United States.
 The cover of this album even features a glass of Waborita that Hagar spent a portion of his concerts creating on stage during his last tour.
A Fistful of Alice is a live album by Alice Cooper.
 It was released in 1997, and was recorded the previous year at Sammy Hagar's Cabo Wabo club in Cabo San Lucas, Mexico.
 Slash plays guitar for part of the album (returning the favor after Cooper guested on "The Garden from the 1991 Guns N' Roses album "Use Your Illusion I") and Cooper says before the song "Desperado" that it was written about Jim Morrison, who died in 1971, the same year Cooper wrote the song.
 Also featured in the album are Rob Zombie on vocals and Sammy Hagar on guitar.
 The last song, "Is Anyone Home?"
, is a studio recording recorded specifically for the album.

"Finish What Ya Started" is a song by Van Halen taken from their 1988 album "OU812".
 Despite the album being seemingly complete, Eddie Van Halen came up with the riff at 2 in the morning and went down to his then-neighbor Sammy Hagar to show it.
 Hagar let Eddie in, and the two played guitars in his balcony until they had a completed song.
 Once Eddie left, Hagar decided to write the lyrics despite being late at night.
 The theme wound up being unfulfilled sex, summed up by Hagar as "blue balls.
 In the song, Eddie Van Halen recorded his guitar part on a Fender Stratocaster plugged direct into the studio mixing console.
 The song is one of only two Van Halen tracks featuring Sammy Hagar playing a rhythm guitar part, which he played on a Gibson acoustic.
