Answer the question at the end by quoting:

Allen Toussaint (; January 14, 1938 - November 10, 2015) was an American musician, songwriter, arranger and record producer, who was an influential figure in New Orleans R&B from the 1950s to the end of the century, described as "one of popular music's great backroom figures." Many musicians recorded Toussaint's compositions, including "Java", "Mother-in-Law", "I Like It
In 1960, Joe Banashak, of Minit Records and later Instant Records, hired Toussaint as an A&R man and record producer. He also did freelance work for other labels, such as Fury. Toussaint played piano, wrote, arranged and produced a string of hits in the early and mid-1960s for New Orleans R&B artists such as Ernie K-Doe, Chris Kenner, Irma Thomas (including "It's Raining"), Art and Aaron Neville, the Showmen, and Lee Dorsey, whose first hit "Ya Ya" he produced in 1961. The early to mid-1960s are regarded as Toussaint's most creatively successful period. Notable examples of his work are Jessie Hill's "Ooh Poo Pah Doo" (written by Hill and arranged and produced by Toussaint), Ernie K-Doe's "Mother-in-Law", and Chris Kenner's "I Like It Like That". A two-sided 1962 hit by Benny Spellman comprised "Lipstick Traces (on a Cigarette)" (covered by the O'Jays, Ringo Starr, and Alex Chilton) and the simple but effective "Fortune Teller" (covered by various 1960s rock groups, including the Rolling Stones, the Nashville Teens, the Who, the Hollies, the Throb, and ex-Searchers founder Tony Jackson). "Ruler of My Heart", written under his pseudonym Naomi Neville, first recorded by Irma Thomas for the Minit label in 1963, was adapted by Otis Redding under the title "Pain in My Heart" later that year, prompting Toussaint to file a lawsuit against Redding and his record company, Stax (the claim was settled out of court, with Stax agreeing to credit Naomi Neville as the songwriter). Redding's version of the song was also recorded by the Rolling Stones on their second album. In 1964, "A Certain Girl" (originally by Ernie K-Doe) was the B-side of the first single release by the Yardbirds. The song was released again in 1980 by Warren Zevon, as the single from the album Bad Luck Streak in Dancing School it reached 57 on Billboard's Hot 100. Mary Weiss, former lead singer of The Shangri-Las, released it as "A Certain Guy" in 2007. Toussaint credited about twenty songs to his parents, Clarence and Naomi, sometimes using the pseudonym "Naomi Neville". These include "Fortune Teller", first recorded by Benny Spellman in 1961, and "Work, Work, Work", recorded by the Artwoods in 1966. Alison Krauss and Robert Plant covered "Fortune Teller" on their 2007 album Raising Sand.

Some context: Philip Alfred Mickelson (born June 16, 1970), nicknamed Lefty, is an American professional golfer. He has won 43 events on the PGA Tour, including five major championships: three Masters titles (2004, 2006, 2010), a PGA Championship (2005), and an Open Championship (2013). Mickelson is one of 16 players in the history of golf to win at least three of the four majors. He has won every major except the U.S. Open, where he has finished runner-up a record six times.
Mickelson attended Arizona State University in Tempe on a golf scholarship and became the face of amateur golf in the United States, capturing three NCAA individual championships and three Haskins Awards (1990, 1991, 1992) as the outstanding collegiate golfer. With three individual NCAA championships, he shares the record for most individual NCAA championships alongside Ben Crenshaw. Mickelson also led the Sun Devils to the NCAA team title in 1990. Over the course of his collegiate career, he won 16 tournaments. Mickelson was the second collegiate golfer to earn first-team All-American honors all four years. In 1990, he also became the first with a left-handed swing to win the U.S. Amateur title. Mickelson secured perhaps his greatest achievement as an amateur in January 1991, winning his first PGA Tour event, the Northern Telecom Open, in Tucson. At age 20, he was only the sixth amateur to win a tour event and the first in over five years after Scott Verplank at the Western Open in August 1985. Other players to accomplish this feat include Doug Sanders (1956 Canadian Open) and Gene Littler (1954 San Diego Open). With five holes remaining, Mickelson led by a stroke, but made a triple-bogey and was then three behind. The leaders ahead of him then stumbled, and he birdied 16 and 18 to win by a stroke. To date, it is the most recent win by an amateur at a PGA Tour event. That April, Mickelson was the low amateur at the Masters Tournament in Augusta, Georgia. With his two-year PGA Tour exemption from the Tucson win, he played in several tour events in 1992 while an amateur but failed to make a cut.

IN: Born and raised in Montgomery, Alabama, Starr's parents were Benjamin Bryan Starr (1910-1985), a labor foreman with the state highway department, and Lula (Tucker) Starr (1916-1995). Starr's early life was marked by hardships; shortly after the start of World War II, his father's reserve unit was activated and in 1942 he was deployed to the Pacific Theater. He was first in the U.S. Army but transferred to the U.S. Air Force for his military career.

Immediately after his retirement as a player, Starr served as the Packers' quarterbacks coach and called plays in 1972 under head coach Dan Devine, when the Packers won the NFC Central division title at 10-4 with Scott Hunter under center. He pursued business interests and was then a broadcaster for CBS for two seasons. When Devine left for Notre Dame after the 1974 season, Starr was hired as head coach of the Packers on Christmas Eve. Upon taking the job, he recognized the long odds of a Hall of Fame player becoming a successful head coach. Initially given a three-year contract, he led the Packers for nine years, the first five as his own general manager. His regular season record was a disappointing 52-76-2 (.408), with a playoff record of 1-1. Posting a 5-3-1 record in the strike-shortened season of 1982, Starr's Packers made their first playoff appearance in ten years (and their last for another 11 years). They defeated the St. Louis Cardinals 41-16 in the expanded wild card round of 16 teams on January 8, 1983, then lost to the Dallas Cowboys 37-26 in the divisional round the following week. He tallied only three other non-losing seasons as Packers coach. After a disappointing 8-8 finish the following year, Starr was dismissed in favor of his former teammate Forrest Gregg, who previously led the Cincinnati Bengals to Super Bowl XVI in the 1981 season and coached the Cleveland Browns before. On January 13, 1984, Starr was named the head coach of the Arizona Firebirds, a proposed expansion team for the NFL. The NFL never granted the would-be ownership group of the Firebirds a team.

did he lead them to any victories?

OUT:
playoff record of 1-1.
