IN: Terry Eugene Bollea was born in Augusta, Georgia on August 11, 1953, the son of construction foreman Pietro "Peter" Bollea (December 6, 1913 - December 18, 2001) and homemaker and dance teacher Ruth V. (nee Moody; 1922 - January 1, 2011). He is of French, Italian, Panamanian, and Scottish descent. When he was one and a half years old, his family moved to Port Tampa, Florida. As a boy, he was a pitcher in Little League Baseball.

Hogan remained WWF World Heavyweight Champion for four years (1,474 days). In front of 33 million viewers, however, Hogan finally lost the title to Andre on the February 5 episode of The Main Event after a convoluted scam involving "The Million Dollar Man" Ted DiBiase and Earl Hebner (who assumed the place of his twin brother Dave Hebner, the match's appointed referee). After Andre delivered a belly to belly suplex on Hogan, Hebner counted the pin while Hogan's left shoulder was clearly off the mat. After the match, Andre handed the title over to DiBiase to complete their business deal. As a result, the WWF World Heavyweight Championship was vacated for the first time in its 25-year history because then WWF President Jack Tunney decreed the championship could not be sold from one wrestler to another. At WrestleMania IV, Hogan participated in a tournament for the vacant WWF World Heavyweight Championship to regain it; he and Andre were given a bye into quarter-finals, but their match resulted in a double disqualification. Later that night in the main event, Hogan came to ringside to stop Andre interfering which helped "Macho Man" Randy Savage defeat Ted DiBiase to win the title. Together, Hogan, Savage, and manager Miss Elizabeth formed a partnership known as The Mega Powers. After Savage became WWF World Heavyweight Champion at WrestleMania IV, they feuded with The Mega Bucks (Andre the Giant and Ted DiBiase) and defeated them at the main event of the first SummerSlam. They then went on to feud with Slick's Twin Towers: Akeem and Big Boss Man. In mid-1988, Hogan wrestled at house shows in singles competition with his "War Bonnet", a red and yellow gladiator helmet with a fist-shaped crest. This was notably used to give Bad News Brown his first WWF loss at a Madison Square Garden house show before it was discarded altogether. The War Bonnet gimmick was revisited in the WWE's online comedy series Are You Serious? in 2012. The Mega Powers began to implode due to Savage's burgeoning jealousy of Hogan and his paranoid suspicions that Hogan and Elizabeth were more than friends. At the Royal Rumble in 1989, Hogan eliminated Savage from the Royal Rumble match while eliminating Bad News Brown, which caused tension, only to be eliminated by The Twin Towers himself. In early 1989, the duo broke up while wrestling The Twin Towers on the February 3 episode of The Main Event, when Savage accidentally collided with Miss Elizabeth during the match, and Hogan took her backstage to receive medical attention, temporarily abandoning Savage, who slapped Hogan and left the ring, where Hogan eventually won the match by himself. After the match, Savage attacked Hogan backstage, which started a feud between the two. Their feud culminated in Hogan beating Savage for his second WWF World Heavyweight Championship at WrestleMania V.

IN: Chicago is an American rock band formed in 1967 in Chicago, Illinois as The Chicago Transit Authority before shortening the name in 1970. The self-described "rock and roll band with horns" began as a politically charged, sometimes experimental, rock band and later moved to a predominantly softer sound, generating several hit ballads. The group had a steady stream of hits throughout the 1970s and 1980s. Since at least 2008, Billboard has shown Chicago to be the "greatest of all time" American band in singles chart success, and since 2015, the "greatest of all time" American band in album chart success as well.

Concurrently with Chicago's existing career, lead vocalist Peter Cetera had begun a solo career. He proposed an arrangement with the band where they would take hiatuses after tours to let him focus on solo work (mirroring that of Phil Collins and Genesis), but the band declined. Cetera ultimately left Chicago in the summer of 1985. He soon topped the charts with "Glory of Love" (the theme song of the film The Karate Kid Part II), and with "The Next Time I Fall" (a duet with Amy Grant). Two more songs reached the Top Ten: a 1988 solo hit called "One Good Woman" (No. 4 U.S.), and a 1989 duet with Cher called "After All" (No. 6 U.S.). In 1992, Cetera released his fourth studio album, World Falling Down, which earned him three hits on the Adult Contemporary charts, including the single "Restless Heart". Cetera's former position was filled by bassist and singer-songwriter Jason Scheff, son of Elvis Presley's bassist Jerry Scheff. Guitarist Chris Pinnick also left the group prior to the recording of the band's next album. For the final Foster-produced album, Chicago 18, the band filled Pinnick's spot with several session guitarists, none of whom became band members. The album was released on September 29, 1986, and included the No. 3 single "Will You Still Love Me?", and Top 20 Pop song "If She Would Have Been Faithful...", in addition to an updated version of "25 or 6 to 4" with a video that got airplay on MTV. Soon after the album was recorded, the band hired guitarist Dawayne Bailey, formerly of Bob Seger's Silver Bullet Band. Bailey and Scheff had previously played in bands together, so Scheff introduced Bailey to the band in time for the Chicago 18 tour. For the 1988 release, Chicago 19, the band had replaced producer Foster with co-producers Ron Nevison, who had recently produced two albums for Heart, and Chas Sanford, who had worked with Rod Stewart and Stevie Nicks. They topped the charts again with the Diane Warren-composed single "Look Away". It was the third and last Chicago single to reach No. 1 on the Hot 100 chart. The song ultimately was named as the "Billboard Hot 100 No. 1 Song of the Year" for 1989. The album also yielded two more Top 10 hits, "I Don't Wanna Live Without Your Love" and "You're Not Alone", both with Champlin singing solo lead for the first time, and the Scheff-sung No. 55 single, "We Can Last Forever," in addition to including the original version of a Top 5 single titled "What Kind Of Man Would I Be?". The latter, also sung by Scheff, was remixed for inclusion on the band's forthcoming greatest hits record (and 20th album), Greatest Hits 1982-1989, and it was this version that became a hit.
