Background: James Alvin Palmer (born October 15, 1945) is a retired American right-handed pitcher who played all of his 19 years in Major League Baseball (MLB) with the Baltimore Orioles (1965-67, 1969-84) and was elected to the Baseball Hall of Fame in 1990. Palmer was the winning pitcher in 186 games in the 1970s, the most wins in that decade by any MLB pitcher. He also won at least twenty games in each of eight seasons and received three Cy Young Awards and four Gold Gloves during the decade. His 268 career victories are currently an Orioles record.
Context: While still an active player, Palmer did color commentary for ABC for their coverage of the 1978, 1980 and 1982 American League Championship Series, 1981 American League Division Series between Oakland and Kansas City, and the 1981 World Series.  From 1985 to 1989, Palmer formed an announcing team with Al Michaels and Tim McCarver at ABC. Palmer announced the 1985 World Series, where he was supposed to team with Michaels and Howard Cosell, whom Palmer had worked with on the previous year's ALCS. McCarver replaced Cosell for the World Series at the last minute after Cosell released a book (I Never Played the Game) that was critical of the ABC Sports team. The team of Palmer, Michaels and McCarver would subsequently go on to call the 1986 All-Star Game (that year, Palmer worked with Michaels on the ALCS while McCarver teamed with Keith Jackson on ABC's coverage of the National League Championship Series), the 1987 World Series, and 1988 All-Star Game as well as that year's NLCS.  Palmer was present at San Francisco's Candlestick Park on October 17, 1989, when the Loma Prieta earthquake hit prior to Game 3 of the World Series. After the 1989 season, ABC lost its contract to broadcast baseball to CBS. Palmer had earned $350,000 from ABC that year for appearing on around ten regular season broadcasts and making a few postseason appearances.  In 1990, the Los Angeles Times reported that Palmer was thinking of pursuing work as a major league manager. Instead, Palmer worked as an analyst for ESPN and as a broadcaster for Orioles games on their local telecasts over WMAR-TV and Home Team Sports.

Background: Expose is an American Latin freestyle vocal group. Primarily consisting of lead vocalists Jeanette Jurado, Ann Curless, and Gioia Bruno, the group achieved much of their success between 1984 and 1993, becoming the first group to have four top ten hits on the Billboard Hot 100 chart from its debut album, including the 1988 #1 hit "Seasons Change". In March 2015, Billboard magazine named the group the eighth most-successful girl group of all-time. The group was popular in dance clubs, mainstream Top 40 and adult contemporary charts in the United States.
Context: During the recording of the group's first studio album Exposure, the personnel of the group changed. Reports vary based on the source. According to People magazine, one of the original singers quit while two of the girls were fired midway through the recording of the first album, but according to Billboard, all three were fired. Arista records felt that the three original singers lacked star potential. Martinee states that he made the decision himself to replace the three girls, while Miller maintains it was all their choice, and Jurado confirms that Lorenzo wanted to leave. Shortly thereafter, Casanas pursued a solo career and Lorenzo pursued other ambitions; they were replaced by Jeanette Jurado and Gioia Bruno. Miller began a solo career; she was replaced by Ann Curless.  Lorenzo returned to the dance charts with the Vendetta Records releases "I Wanna Know" in 1988, and "Stop Me if I Fall in Love" in 1990, while Laurie Miller released the 12" single "Parallels" on Atlantic Records and a second single "Love is a Natural Magical Thing" on Meet Me In Miami Records. Laurie evolved into a headline performer frequently showcasing her talents on cruises with a more intimate jazz style, and formed her own entertainment company called Xica productions.  Casanas later resurfaced as a solo artist (Sandee) and released a solo album, Only Time Will Tell, which garnered the club hits "You're The One", "Love Desire", and the Clivilles & Cole-produced bassline-heavy hit "Notice Me". She continued to tour actively in dance clubs and freestyle shows, until her death on December 15, 2008, of a seizure at the age of 46. All three original members: Casanas, Lorenzo and Miller later contributed vocals on songs on the Miami group Will to Power's eponymous 1988 debut album. Gioia Bruno also provided lead vocals on Will to Power's 2004 album, Spirit Warrior.
