Context paragraphs:
The Happening (song): "The Happening" is a 1967 song recorded by Motown artists The Supremes.  The song served as the theme song of the 1967 Columbia Pictures film "The Happening", and was released as a single by Motown at the time of the film's release that spring.  While the movie flopped, the song peaked at number-one on the "Billboard" Hot 100 pop singles chart in May, becoming The Supremes' tenth number-one single in the United States, peaking in the top 10 on the UK Pop Chart at number six, and in the top 5 in the Australian Pop Chart and in the Dutch Pop Chart.

Run for the Roses (song): "Run for the Roses" is a song on the album "The Innocent Age", written and recorded by singer/songwriter Dan Fogelberg in 1981.  Released as a single the following year, it peaked at number 18 on the "Billboard" Hot 100.  It has since been used as an unofficial theme for the Kentucky Derby.  The chorus mentions "the chance of a lifetime in a lifetime of chance" at once describing the experience of horse racing and life itself.

Ben (song): "Ben" (often referred to as "Ben's Song"), is a song written by Don Black and composed by Walter Scharf for the 1972 film of the same name (the sequel to the 1971 killer rat film "Willard").  It was performed in the film by Lee Montgomery and by Michael Jackson over the closing credits.  Jackson's single, recorded for the Motown label in 1972, spent one week at the top of the U.S. pop chart. " Billboard" ranked it as the No. 20 song for 1972.  It also reached number one on the Australian pop chart, spending eight weeks at the top spot.  The song also later reached a peak of number seven on the British pop chart.

Windows and Walls: Windows and Walls is the eighth album by American singer-songwriter Dan Fogelberg, released in 1984 (see 1984 in music).  The first single, "The Language of Love", reached  13 on the U.S. "Billboard" Hot 100 chart.  Although the follow-up, "Believe in Me", missed the Top 40 of the pop chart, peaking at No. 48, it became the singer's fourth No. 1 song on the "Billboard" adult contemporary chart.

Stars (Dan Fogelberg song): "Stars" is a 1972 ballad from Dan Fogelberg's debut album, "Home Free", and the second track on the album.

The Innocent Age: The Innocent Age is the seventh album by American singer-songwriter Dan Fogelberg, released in 1981 (see 1981 in music).  It was also one of his most successful albums; three of his four Top 10 singles on the "Billboard" pop chart ("Hard to Say" (no. 7), "Same Old Lang Syne" (no. 9), and "Leader of the Band" (no. 9)) were from this album, as well as another Top 20 single in "Run for the Roses" (no. 18).  All four also reached the Top 10 on the "Billboard" adult contemporary chart, with "Leader of the Band" reaching number 1 on that chart.  The album also includes his song "Times Like These" from the 1980 "Urban Cowboy" soundtrack.  "The Innocent Age" drew its inspiration from Thomas Wolfe's major novel "Of Time and the River."

Souvenirs (Dan Fogelberg album): Souvenirs is the second studio solo album by the American rock singer-songwriter Dan Fogelberg.  The album was released in late 1974, on the label Epic Records.

Same Old Lang Syne: "Same Old Lang Syne" is a song written and sung by Dan Fogelberg released as a single in 1980.  It was also included on his 1981 album "The Innocent Age".

The song peaked at #9 on the "Billboard" Hot 100 Chart and is now frequently played during the holiday season and alongside traditional Christmas songs.

Mirage (Fleetwood Mac album): Mirage is the 13th studio album by British-American rock band Fleetwood Mac, released on June 18, 1982.  This studio effort's soft rock sound stood in stark contrast to its more experimental predecessor, 1979's "Tusk".  "Mirage" yielded several hit singles: "Hold Me" (which peaked at #4 on the US "Billboard" Pop Chart, remaining there for seven weeks), "Gypsy" (#12 US Pop Chart), "Love in Store" (#22 US Pop Chart), "Oh Diane" (which reached #9 in the UK), and "Can't Go Back" (issued on 7" and 12" in the UK).
