Question:
Robert Walls (born 21 July 1950) is a former Australian rules footballer who represented Carlton and Fitzroy in the Victorian Football League (VFL) during the 1960s and 1970s. In a playing career that spanned three decades Robert played a combined 259 games and kicked a total of 444 goals. Throughout the 1980s and 1990s he continued to coach in the VFL/AFL for a total of 347 games across four different clubs. As a coach, his greatest achievement came in 1987 when he coached Carlton to the 1987 VFL premiership, the same club he won premierships with as player in 1968, 1970 and 1972.
After he retired as a player, Walls immediately took over as coach of Fitzroy. With a major clean-out of older players who were clearly "past it" in the club's disappointing 1980 season, Walls lifted the Lions to their best era since winning a premiership in 1944. Robert would coach Fitzroy Football Club for 115 games (60 wins - 54 losses - 1 draw).  They improved from last in 1980 to fifth at the end of the home-and-away season in 1981, securing their finals berth with an upset win over Collingwood and then beating Essendon in the Elimination Final before failing by the narrowest of margins in the First Semi against the Magpies. 1982 was relatively disappointing due to a poor start, but with players like Gary Pert and Paul Roos from the club's recruiting zones and South Australian recruit Matt Rendell growing into stars, the Lions were back as a force at the end of the season. 1983 saw the Lions emerge after five rounds as favourites for the premiership and maintain that favouritism with a sensational win in a top-of-the-table clash with North by 150 points with Rendell kicking eight goals besides destroying Gary Dempsey in the ruck. However, inevitable overconfidence saw the Lions lose form and finish fourth after losing two hard-fought finals.  1984, with injuries plaguing the club and its lack of depth apparent, was initially disappointing but a remarkable recovery saw them enter the five after the final round only to be crushed by Collingwood. In 1985, the Lions' financial crisis emerged to threaten their future and this, along with more injuries, caused them to drop to ninth with only seven wins and two losses to last-placed St Kilda. After this, Walls moved to his former club Carlton in a swap with David Parkin.

input: After the Eagles disbanded, Frey achieved solo success in the 1980s, especially with two No. 2 hits. In 1984, he recorded in collaboration with Harold Faltermeyer the worldwide hit, "The Heat Is On", the main theme from the Eddie Murphy action comedy film Beverly Hills Cop; then, Frey performed "You Belong to the City" (from the television series Miami Vice, the soundtrack of which stayed on top of the U.S. album charts for 11 weeks in 1985). His other contribution to the soundtrack, "Smuggler's Blues", hit No. 12 on the Billboard Hot 100. During his solo career, Frey had 12 charting songs in the U.S. Top 100. Eleven of those were written with Jack Tempchin who also wrote "Peaceful Easy Feeling".  Frey was the first choice to record "Shakedown", the theme for the film Beverly Hills Cop II. Frey did not like the lyrics and then came down with laryngitis, so the song was given to Bob Seger. After the song went to number one, Frey called to congratulate Seger, saying "At least we kept the money in Michigan!"  Frey also contributed the song "Flip City" to the Ghostbusters II soundtrack, and "Part of Me, Part of You" to the soundtrack for Thelma & Louise. In 2005, he appeared on B.B. King & Friends: 80 on the track "Drivin' Wheel".  In the late 1990s, Frey founded a record company, Mission Records, with attorney Peter Lopez. Frey never released any of his own work on the label and the company has since disbanded.  On May 8, 2012, he released his first solo album in 20 years, After Hours, featuring covers of pop standards from the 1940s to the 1960s.

Answer the question at the end by quoting:

William Martin Joel was born in the Bronx on May 9, 1949, and was raised in Levittown, New York in the town of Oyster Bay. In 1963 when zip codes were assigned, the section of Levittown in Oyster Bay was given a Hicksville, New York zip code and has since been part of Hicksville. Joel's father, Howard (born Helmuth) Joel, a classical pianist, was born in Germany, to a Jewish family, the son of a merchant and manufacturer, Karl Amson Joel. Howard emigrated to Switzerland and later to the United States (via Cuba, as immigration quotas for German Jews prevented direct immigration at the time) to escape the Nazi regime.
In 1974, Joel recorded his second Columbia album in Los Angeles, Streetlife Serenade. His manager at the time was Jon Troy, an old friend from the New York neighborhood of Bedford-Stuyvesant; Troy would soon be replaced by Joel's wife Elizabeth. Streetlife Serenade contains references to suburbia and the inner city. It is perhaps best known for "The Entertainer", a No. 34 hit in the US. Upset that "Piano Man" had been significantly cut for radio play, Joel wrote "The Entertainer" as a sarcastic response: "If you're gonna have a hit, you gotta make it fit, so they cut it down to 3:05." Although Streetlife Serenade is often considered one of Joel's weaker albums (Joel dislikes it himself), it contains the notable songs "Los Angelenos" and "Root Beer Rag", an instrumental that was a staple of his live set in the 1970s.  In late 1975, Joel played piano and organ on several tracks on Bo Diddley's The 20th Anniversary of Rock 'n' Roll all-star album.  Disenchanted with Los Angeles, Joel returned to New York City in 1975 and recorded Turnstiles, the first album he recorded with the group of hand-picked musicians who became the Billy Joel Band. Produced by James William Guercio (then Chicago's producer), Turnstiles was first recorded at Caribou Ranch with members of Elton John's band. Dissatisfied with the result, Joel re-recorded the songs and produced the album himself.  "Say Goodbye to Hollywood" was a minor hit; Ronnie Spector recorded a cover as did Nigel Olsson, then drummer with Elton John. In a 2008 radio interview, Joel said that he no longer performs the song because singing it in its high original key "shreds" his vocal cords; however, he did finally play it live for the first time since 1982 when he sang it at the Hollywood Bowl in May 2014. Though never released as a single, "New York State of Mind" became one of Joel's best-known songs; Barbra Streisand and Tony Bennett have each recorded covers (Bennett's a duet with Joel on Playing with My Friends: Bennett Sings the Blues). Other notable songs from the album include "Summer, Highland Falls", "Miami 2017 (Seen the Lights Go Out on Broadway)", "Say Goodbye to Hollywood", (a live version of which became a Top 40 hit), and "Prelude/Angry Young Man", a concert mainstay.
