 "Perhaps Love" is the only song on the album with Denver's vocals alongside Domingo's.
 However, Denver also appears on the album's cover version of his composition "Annie's Song", where he accompanies Domingo on guitar.
 Released as a single with "Annie's Song" on the B side, "Perhaps Love" peaked at #22 on the U.S. Adult Contemporary chart and #59 on the "Billboard" Hot 100 in 1982.
 Remaining in print, the song sold almost four million copies by 2008.

 (The Erato label released the fourth Christmas in Vienna concert from 1995 that Domingo held with José Carreras and Natalie Cole.)
 Recorded in December 1998, it also includes the French singer Patricia Kaas and the Mexican singer Alejandro Fernández with the Vienna Symphony Orchestra directed by Steven Mercurio.

Plácido Domingo Jr. (born 1965), also known as Plácido and Plácido Jr., is a Mexican-Spanish singer, songwriter, composer, and record producer.
Josefa "Pepita" Embil Echániz (Basque: "Josefa Enbil Etxaniz"; February 28, 1918—August 28, 1994) was a Spanish Basque soprano who starred in zarzuela and operetta productions throughout Spain and Latin America.
 Known as the "Queen of Zarzuela," she is especially remembered for her son, the internationally famous operatic tenor Plácido Domingo, whose early career she helped to nurture.
 Embil began her professional career singing as a soloist in choirs, including the Basque national choir, Eresoinka, which based itself in France during the Spanish Civil War.
 While still in her twenties, she appeared in the world premieres of several new zarzuelas.
 She collaborated with some of the most prominent Spanish composers of the 1940s, including Federico Moreno Torroba, Jacinto Guerrero, and Pablo Sorozábal.
 In late 1948, she moved to Mexico with her baritone husband, Plácido Domingo Ferrer.
 In Mexico they ran a successful zarzuela company of their own, which toured throughout the Americas.
 Over the course of her career, Embil made several recordings, primarily of zarzuela music.
The Passions are an American doo-wop group from Bensonhurst, Brooklyn.
 The quintet recorded a few demos in 1958, at which time Tony, Albee and Vinny began looking for replacements who were more career-minded.
 Another group in Bensonhurst had what they needed; when the three Sinceres heard Runarounds lead singer Jimmy Gallagher, they knew he was the one for them (Jimmy’s previous group, the Palladiyms, included Joe DiBenedetto, who later formed "The Four-evers".)
The Sinceres weren’t sure how to approach Jimmy, so they followed him home one night and knocked on his door.
 After convincing his mother that they only wanted to sing with her son, not mug him, the foursome went to a nearby park and ended up harmonizing for hours.
 They were now a quartet, with Jimmy on lead, Tony on first tenor, Albee on second tenor, and Vinnie on baritone.n 1959, while the Mystics were recording "Hushabye" at their first session, their friend Tony Armato was there cheering them on promoting his own group to their manager, Jim Gribble.
 Gribble soon signed the Sinceres and renamed them the Passions.
 He gave them a demo by a duo of studio singers who called themselves the Cousins.
 The song was "Just to Be with You" written by Mary Kalfin.
 The Cousins were Paul Simon and Carole King.
 By the time the group recorded "Gloria" Vinny had left and been replaced by Gallagher’s friend Lou Rotondo.
 Also in 1960 Lou Rotondo and Albie Galione, along with Albie Contrera of the Mystics, sang behind Clay Cole on "Here, There, Everywhere" (Roulette), single that became popular in the New York area.
 Audicon Records lost the group’s next release, the harmony rocker "Made for Lovers."
 The group recorded a few more sides for Audicon which were leased to Jubilee and Octavia.
 Released in August 1959 on Sol Winkler’s Audicon label, the Passions’ impeccable harmonies and Gallagher’s impassioned lead put "Just to Be with You" on radios across America.
 It was a top 20 hit in many eastern cities and it charted nationally, rising to number 69.
 The follow-up out of Audicon’s 1674 Broadway digs was twice as good.
 Both sides—the harmony filled "I Only Want You" and the beautiful Billy Dawn Smith ballad "This Is My Love" –vied for radio play and sales throughout the states.
 They were managed by Jim Gribble who managed several doo-wop groups including the Mystics and The Jarmels, and worked with producer songwriter Stan Vincent.
 In the late 1990s, they reunited with the Mystics and the Classics for the Brooklyn Reunion Show.
 Lead singer Jimmy Gallagher left the Passions in 1960 to join the Navy, but later sang with The Legends of Doo Wop in 1998.

Rebecca Luker (born April 17, 1961) is an American actress, singer, and recording artist who has appeared in several musical theatre productions on Broadway.

The Private Lives of the Three Tenors is a gossip biography of tenors Plácido Domingo, Luciano Pavarotti, and José Carreras by Marcia Lewis, the mother of Monica Lewinsky.
 The book received high-level publicity during the 1998 Lewinsky scandal, as journalists compared Lewis' "hints" of an affair with popular opera singer, Plácido Domingo, to Lewinsky’s then-unproven allegations against U.S. President Bill Clinton.
 Domingo insisted that he only knew Lewis socially.
