"Blue Collar Man (Long Nights)" is the first single that Styx released from the Pieces of Eight (1978) album. Released in 1978, the single came in two 7" vinyl formats: one with the b-side "Superstars" (a track from The Grand Illusion) and a second single with the instrumental album track "Aku-Aku" as the b-side. Some printings of the single were also issued in a translucent blue vinyl, which are now highly sought after collectors items. As read in a Circus magazine (or the like) of the time, the song was composed by Tommy Shaw after hearing the sound of his motor boat engine when it failed to start. He said it sounded like a good riff to a song. According to Billboard Magazine it has "riveting high energy guitar licks and a powerful lead vocal." The song reached #21 in the United States in November 1978, and spent two weeks at No. 9 on the Canada RPM Top 100 Singles chart.
A promo video for this song was filmed by director Bruce Gowers of the band performing on a soundstage. Videos were also shot for "Sing for the Day" and "I'm OK".
