Question: Who composed a side-long title track from Rush's 1976 album?

Context paragraphs:
Year of the Cat (song): "Year of the Cat" is a single by singer-songwriter Al Stewart, released in July 1976.  The song is the title track of his 1976 album "Year of the Cat", and was recorded at Abbey Road Studios, London in January 1976 by engineer Alan Parsons.  The song reached #8 on the "Billboard" Hot 100 in March 1977.  Although Stewart's highest charting single on that chart was 1978's "Time Passages", "Year of the Cat" has remained Stewart's signature recording, receiving regular airplay on both classic rock and folk rock stations.

2112 (album): 2112 (pronounced ""twenty-one twelve"") is the fourth studio album by Canadian rock band Rush.  Released on 1 April 1976, it features the seven-part title suite composed by Geddy Lee and Alex Lifeson, with lyrics written by Neil Peart telling a dystopian story set in the year 2112.  It is sometimes described as a concept album although the songs on the second side are unrelated to the suite.  Rush repeated this arrangement on the 1978 album "Hemispheres".

Lost Without Your Love (song): "Lost Without Your Love" is a song written and composed by David Gates, and originally recorded by the pop-rock group Bread, of which Gates was the leader and primary music producer.  It is the title track of Bread's 1976 album, and became their final Top 10 hit.

The Thin White Duke: The Thin White Duke was David Bowie's 1975 and 1976 persona and character.  He is primarily identified with Bowie's 1976 album "Station to Station" and is mentioned by name in the title track.  However, Bowie had begun to adopt the "Duke" persona during the preceding "Young Americans" tour and promotion in 1975.  The persona's look and character are somewhat based on Thomas Jerome Newton, the titular humanoid alien played by Bowie in the 1976 film "The Man Who Fell to Earth".

2112 (song): "2112" (pronounced twenty-one twelve) is a side-long title track from Canadian rock band Rush's 1976 album of the same name.  The overture and the first section, "Temples of Syrinx", were released as a single and have been featured in most of Rush's setlists since.  The "sci-fi" sounds in the beginning of the song were created using an ARP Odyssey synthesizer and an Echoplex tape delay.  On the "2112 / Moving Pictures" episode of the documentary series "Classic Albums", producer Terry Brown states the synth intro is composed of various parts played by Hugh Syme that were put together in a collage.  Since 1997, when any parts of the song are performed live, they are transposed down one full step, as heard on every live album and DVD from "Different Stages" forward.

Time Passages: Time Passages is the eighth studio album by Al Stewart, released in September 1978.  It is the follow-up to his 1976 album "Year of the Cat".  The album, like 1975's "Modern Times" and 1976's "Year of the Cat", was once again produced by Alan Parsons.  The album's title track (which, when edited, reached #7 on the "Billboard" charts) and "End of the Day" were both co-written by Peter White.  The title track also reached #1 on the Billboard Adult Contemporary charts for 10 weeks.

Don't Stop Believin' (Olivia Newton-John song): "Don't Stop Believin'" is the title track from the 1976 album by Olivia Newton-John.  The song was written by John Farrar and peaked at number thirty-three on the "Billboard" Hot 100.  It was her seventh number one on the Easy Listening chart, spending one week at the top of the chart in September 1976.  The single also went to number fourteen on the country chart.

Heaven and Earth and the Stars: Heaven and Earth and the Stars is a 1976 album by Lulu.  It was the second and last of her albums to be released on the Chelsea record label, which ceased production this year.  Like the previous album, it was produced by Wes Farrell, apart from two tracks "The Man Who Sold the World" and "Watch That Man" which were produced by David Bowie and Mick Ronson.  The former had been a big hit for Lulu, reaching No.3 in the UK, although had been released more than two years before this album's release.  Also from 1974 was Lulu's theme song for the James Bond film, "The Man with the Golden Gun", produced by John Barry.  Another hit single featured on this album was "Take Your Mama for a Ride", which had been a No.37 hit in 1975.  Despite these inclusions, the album failed to chart, being too late to cash in on the hits.  Further singles released from the album were "Boy Meets Girl" and the title track, bring the total single releases to five - half the album.

Coney Island Baby: Coney Island Baby is a 1976 album by Lou Reed, released in January by RCA Records.  It is also the title of a song on that album.  Many of the album's songs were inspired by Reed's girlfriend and muse at the time, a trans woman named Rachel.  According to Aidan Levy, "Coney Island Baby" was "as much a love letter to Rachel as it was to the nostalgic Coney Island of the mind."  The album's title track directly references Rachel with the line: "I'd like to send this one out to Lou and Rachel, and all the kids at P.S. one ninety-two."  It was originally presented as a poem entitled "The Coach and Glory of Love" in "The Harvard Advocate: Journal of Fiction and Poetry" in 1971.

The Third Reich 'n Roll: The Third Reich 'n Roll is a 1976 album by the U.S. avant-garde rock group The Residents.  Their second (officially) released album, it is a parody and satire of pop music and commercials from the 1960s.  The work consists of two side-long pastiches of various songs from the period.  Some are obvious, while others are almost unrecognizable.  Although none of the songs are named on the album, The Residents' first website listed the tracks as the following:
