Question:
Rabbitt was born to Irish immigrants Mae (nee Joyce) and Thomas Michael Rabbitt in Brooklyn, New York in 1941, and was raised in the nearby community of East Orange, New Jersey. His father was an oil-refinery refrigeration worker, and a skilled fiddle and accordion player, who often entertained in local New York City dance halls. By age twelve Rabbitt was a proficient guitar player, having been taught by his scoutmaster, Bob Scwickrath. During his childhood Rabbitt became a self-proclaimed "walking encyclopedia of country music".
Rabbitt was employed as a mental hospital attendant in the late 1950s but, like his father, he fulfilled his love of music by performing at the Six Steps Down club in his hometown. He later won a talent contest and was given an hour of Saturday night radio show time to broadcast a live performance from a bar in Paterson, New Jersey. In 1964, he signed his first record deal with 20th Century Records and released the singles, "Next to the Note" and "Six Nights and Seven Days". Four years later, with $1,000.00 to his name, Rabbitt moved to Nashville where he began his career as a songwriter. During his first night in the town, Rabbitt wrote "Working My Way Up to the Bottom", which Roy Drusky recorded in 1968. To support himself, Rabbitt worked as a truck driver, soda jerk and fruit picker while in Nashville. He was ultimately hired as a staff writer for the Hill & Range Publishing Company and received a salary of $37.50 per week. As a young songwriter, Rabbitt socialized with other aspiring writers at Wally's Clubhouse, a bar in Nashville; he said that he and the other patrons had "no place else to go."  Rabbitt became successful as a songwriter in 1969 when Elvis Presley recorded his song "Kentucky Rain". The song went gold and cast Rabbitt as one of Nashville's leading young songwriters. While eating Cap'n Crunch, he penned "Pure Love", which Ronnie Milsap rode to No. 1 in 1974. This song led to a contract offer from Elektra Records.  Rabbitt signed with Elektra Records in 1975. His first single under that label, "You Get To Me" made the top 40 that year, and two songs in 1975, "Forgive and Forget" and "I Should Have Married You" nearly made the top 10. These three songs along with a recording of "Pure Love" were included on Rabbitt's self-named debut album in 1975. In 1976 his critically acclaimed Rocky Mountain Music album was released, which handed Rabbitt his first No. 1 country hit with the track "Drinkin' My Baby (Off My Mind)". In 1977 his third album, Rabbitt was released, which made the top 5 on Country Albums chart. Also in 1977 the Academy of Country Music named Rabbitt "Top New Male Vocalist of the Year". By that time he had a good reputation in Nashville, and was being compared by critics to singer Kris Kristofferson. In 1977, at Knott's Berry Farm, Eddie Rabbitt appeared at the CMA and sang several of his songs from the album Rocky Mountain Music. He won the award of Top New Male Vocalist of the Year.

Answer the question at the end by quoting:

Born in Pizzoferrato, Abruzzo, Italy on October 6, 1935, Sammartino was the youngest of seven brothers and sisters. Four older siblings died during his time in Italy. During his childhood, Sammartino's family hid from German soldiers in a mountain called Valla Rocca, during the latter stages of World War II. During this time, Sammartino's mother, Emilia, would sneak into their German-occupied town for food and supplies.
Despite a very long series of rematches against Graham, Sammartino was unable to regain the title. His final attempt was in Philadelphia, just a few days before Graham was scheduled to lose the title to Bob Backlund. The Philly match was the only documented instance of Sammartino losing a steel cage match, as he lost by accidentally knocking a bloody and battered Graham through the cage door.  After his second reign ended, Sammartino leisurely toured the U.S. and the world. He wrestled then NWA World Heavyweight Champion Harley Race to a one-hour draw in St. Louis. He also wrestled and defeated Blackjack Mulligan, Lord Alfred Hayes, Dick Murdoch, Kenji Shibuya, and "Crippler" Ray Stevens. Also during this time, Sammartino began serving as color commentator for the WWF's syndicated programs, WWF Championship Wrestling and WWF All-Star Wrestling.  On January 22, 1980, his former student Larry Zbyszko turned on him at the World Wrestling Federation's Championship Wrestling show. Sammartino, shocked and hurt by Zbyszko's betrayal, vowed to make Zbyszko pay dearly. Their feud culminated on August 9, 1980, in front of 36,295 fans at Shea Stadium. As the main event of 1980's Showdown at Shea, Sammartino defeated Zbyszko inside a steel cage. In his autobiography, Hulk Hogan claimed that his match with Andre the Giant was the real reason for the huge draw at Shea Stadium; however, the feud between Sammartino and Zbyszko sold out everywhere in the build-up to the show. In contrast, Hogan and Andre headlined exactly one card in White Plains, New York before they wrestled at Shea, and they drew a paltry 1,200 in a building that held 3,500.  Sammartino retired from North American wrestling full-time in 1981, in a match that opened the Meadowlands Arena in East Rutherford, New Jersey. Sammartino pinned George "The Animal" Steele in his match. Sammartino then finished up his full-time career by touring Japan.

What happened after he turned on him?
Sammartino, shocked and hurt by Zbyszko's betrayal, vowed to make Zbyszko pay dearly.
