Songfacts®:

• No, she not a one-hit wonder; Stacey Q (born as Stacey Swain) had another Billboard charter with "We Connect" in 1987 (#35), but "Two of Hearts" is definitely her signature song and greatest claim to fame.
  
  Stacey Q was the quintessential Southern California girl. Born in Fullerton, Orange County, she worked for years as an entertainer at Disneyland (she was a dancing puppet in the parade), then auditioned at the Ringling Brothers circus and became a showgirl there, and then a mahout (an elephant rider - Joan Armatrading got that word into a lyric). Then her musician boyfriend introduced her to the Casbah Recording Studio (Fullerton California again), where she met the producer Jon Saint James, who formed a Techno group with her called Q. The group broke up in the early '80s, but Swain got a record deal in 1985, and with Saint James as her producer, recorded as Stacey Q, a reference to their earlier band name. Saint James was a big fan of the German electronic band Kraftwerk; you can hear that influence in this song.
• In America, the single sold one million copies in 1986, making it one of the more successful songs of that year. Stacey Q was a California phenomenon until she appeared on the sitcom The Facts of Life in the 1986 episode "Off-Broadway Baby" to perform "Two Of Hearts." This earned her national attention, especially among teenage girls.
  
  Would you believe after all that, she pulled a Beatles and fled to Tibet to study under monks and become a Buddhist? That led to her album Boomerang (her comeback album, get it?), where she even covered George Harrison's "My Sweet Lord." Boomerang went boom, and Stacey Q has faded into obscurity.
• Three different songs called "Two Hearts" have made the Top 40 in America, including a #1 hit for Phil Collins, but this is the first hit song to use the playing card theme for the story of a couple uniting in harmony. It's also the second-biggest hit with a playing card description in the title, after Juice Newton's version of "Queen of Hearts," although metal fans will always prefer "Ace Of Spades" by Motorhead.
  
  In cards, the suit of hearts is derived from the tarot deck suit of cups. In tarot, the two of cups is a minor arcana card which normally indicates love, relationship, or a partnership such as a business venture, but reversed means a breakup or fragmenting of a foundation.
• The songwriting credits on this one were the subject of a legal dispute. The song was initially credited to John Mitchell, Sue Gatlin, and Tim Greene, but after legal action, Mitchell is now credited as the sole songwriter of "Two Of Hearts."
• This song was used in two episodes of It's Always Sunny in Philadelphia: "The Gang Escapes" (2018) and "The Gang Gets Whacked: Part 2" (2007). It's also in episodes of Scream Queens ("Chainsaw" - 2015) and RuPaul's Drag Race ("The Snatch Game" - 2010) and appears in these movies:
  
  Hot Rod (2007)
  Party Monster (2003)
  Little Nicky (2000)
  Nowhere (1997)
