Some context: Tha Dogg Pound is an American hip hop duo formed in 1992, made up of West Coast rappers Kurupt and Daz Dillinger (formerly Dat Nigga Daz). They were signed to Death Row Records in their early careers and were key to the label's success. The duo made their first appearance on Dr. Dre's highly acclaimed debut album The Chronic (1992), appearing on several songs. They also appeared on Snoop Dogg's debut album Doggystyle (1993), and the Death Row soundtracks Murder Was the Case and Above the Rim.
Over the years Tha Dogg Pound had beef with Bone Thugs-N-Harmony, due to Death Row Records being embroiled in a feud with Eazy-E's Ruthless Records. Tha Dogg Pound made a diss towards The Bone Thugs, on the song "Dogg Pound Gangstaz", with Kurupt's line "Ain't got no love for no hoes in harmony." In response Layzie Bone shot back on the track "Shotz to tha Double Glock" with the line "Dogg Pound hoes it's on." "Krayzie Bone says "Gotta find these 'Row Hoes" in the song "Mo' Murda" off the East 99 album. The feud ended when Snoop Dogg and Kurupt were featured on Krayzie Bone's album Thug Mentality 1999 in the song "The War Iz On." Kurupt was featured on Flesh-N-Bone's song "Kurupted Flesh" on the 5th Dog Let Loose. Krayzie Bone also featured on Daz Dillinger's 2008 solo album Only on the Left Side on the song "Meal Ticket" and later on the song "Money Fold'N" on Tha Dogg Pound's 2009 album That Was Then, This Is Now.  Tha Dogg Pound were also involved in a feud with B.G. Knocc Out & Dresta. In response to Eazy-E's Real Muthaphukkin G's and Kokane & Cold 187um's "Don't Bite The Funk", Tha Dogg Pound along with Snoop Dogg made a track called "What Would You Do" with such lines as: "Fuck B.G. Knocc Out and every nigga down with him." Later B.G. Knocc Out & Dresta retaliated with the song "D.P.G. Killa", on their debut album Real Brothas. They have since squashed the beef and released a song called "Blaze It Up", as a bonus track on Tha Dogg Pound's Dogg Chit album.  The duo engaged in yet another conflict, the beef Suge and new signee 2Pac initiated against Bad Boy Entertainment's Puff Daddy and Notorious B.I.G.; Daz and Kurupt would expand the feud to include Capone-N-Noreaga, Tragedy Khadafi and Mobb Deep with their Snoop-assisted single "New York, New York."

Some context: Michael Anthony Orlando Cassavitis (born April 3, 1944), known professionally as Tony Orlando, is an American singer, songwriter, producer, music executive, and actor, best known as the lead singer of the group Tony Orlando and Dawn in the 1970s. Orlando formed the doowop group The Five Gents in 1959 at the age of 15, with whom he recorded demos, and got the attention of music publisher and producer Don Kirshner. Kirshner hired him to songwrite at 1650 Broadway, Manhattan as part New York's thriving Brill Building songwriting community, along with other songwriters Carole King, Neil Sedaka, Toni Wine, Barry Mann, Cynthia Weil, Bobby Darin, Connie Francis, and Tom and Jerry, who didn't make it in the office until they later changed their name to Simon and Garfunkel. Orlando was also hired to sing on songwriter demos, and singles released with Orlando as a solo artist began to hit the charts in the US and the UK beginning in 1961 with "Halfway to Paradise" and "Bless You" when he was 16.
Tony Orlando was born Michael Anthony Orlando Cassavitis on April 3, 1944, the son of a Greek father and a Puerto Rican mother. He spent his earliest years in Hell's Kitchen, New York. In his teenage years, the family moved to Union City, New Jersey and later Hasbrouck Heights, New Jersey.  Orlando's musical career started with The Five Gents, a doo-wop group he formed in 1959 at age 15, with whom he recorded demo tapes. He got the attention of music publisher and producer Don Kirshner, who hired him to songwrite in an office across from New York's Brill Building, along with Carole King, Neil Sedaka, Toni Wine, Barry Mann, Bobby Darin, Connie Francis, and Tom and Jerry, who didn't make it in the office until they changed their name to Simon and Garfunkel. Kirshner also hired Orlando to record songwriter demos as a solo artist, and his first success came at the age of 16 when he charted in the US and UK with the hits "Bless You" and "Halfway To Paradise." He also appeared at the Brooklyn Paramount Theater with DJ Murray the K. Orlando also had four records that "Bubbled Under" the Hot 100: "Chills" in 1962, "Shirley" and "I'll Be There" in 1963, and "I Was A Boy (When You Needed A Man)" as by Billy Shields in April 1969. Gerry Goffin and Jack Keller wrote a doo-wop version of Stephen Foster's song "Beautiful Dreamer" for Orlando. Released as a single in 1962, the song was picked up by the Beatles who included it in their set lists on the Beatles Winter 1963 Helen Shapiro Tour; a recorded version was released on their 2013 album On Air - Live at the BBC Volume 2.  New Colony Six recorded an Orlando composition, "I'm Just Waitin' (Anticipatin' For Her To Show Up)", which charted locally in Chicago and "Bubbled Under" the Hot 100 in July 1967. That year, Clive Davis hired Orlando as general manager of Columbia Records publishing subsidiary April-Blackwood Music. By the late 1960s, Orlando had worked his way up to vice president of a larger publishing company, CBS Music, where he signed, co-wrote with and produced Barry Manilow (under the name "Featherbed") and worked with James Taylor, the Grateful Dead, Laura Nyro and other artists. In the summer of 1969 he recorded with the studio group Wind and had a #28 hit that year with "Make Believe" on producer Bo Gentry's Life Records. Orlando was experiencing success, primarily as a music executive, and Davis pretended not to notice when Orlando accepted a $3,000 advance and sang lead vocals on a song called "Candida" as a favor for two producer friends. If the record failed, Orlando didn't want it to affect his reputation, so he used a pseudonym: Dawn.
