Question: When Smokey Sings is a song that is in homage to the frontman of what vocal group?
Context: William "Smokey" Robinson Jr. (born February 19, 1940) is an American singer, songwriter, record producer, and former record executive.  Robinson was the founder and front man of the Motown vocal group the Miracles, for which he also served as the group's chief songwriter and producer.  Robinson led the group from its 1955 origins as the Five Chimes until 1972 when he announced a retirement from the group to focus on his role as Motown's vice president. The Dells were an American R&B vocal group.  Formed in high school in 1952 by founding members Marvin Junior, Verne Allison, Johnny Funches, Chuck Barksdale, and Mickey and Lucius McGill, under the name the El-Rays, they released their first recording in 1954, and two years later, had their first R&B hit with "Oh What a Night".  After disbanding due to a near-fatal car crash in 1958, the band reformed in 1960 with Funches being replaced by Johnny Carter.  This lineup remained together until Carter's 2009 death.  The Dells were inducted to the Rock and Roll Hall of Fame and the Vocal Group Hall of Fame in 2004.  The vocal group performed until illness forced longtime lead singer Marvin Junior and bass vocalist Chuck Barksdale into retirement, ending the group's 60-year run. "After All" is a 1960 song written by Smokey Robinson and originally recorded and released by The Miracles on the Tamla label.  It was later covered as an unreleased single by The Supremes for Tamla; it was canceled in favor of the single "Buttered Popcorn", and their cover wasn't released until it appeared on the 2000 box set, "The Supremes".  The song is noted for both groups' unusual choices for leads.  For the Miracles' version it serves as a rare lead for Claudette Rogers Robinson, instead of the group’s main lead, Claudette's husband, Smokey Robinson.  In the Supremes' case it is their only single to feature Barbara Martin singing on lead vocals (although she does have a spoken line during the song "(He's) Seventeen").  Florence Ballard, Mary Wilson, and Diana Ross sing verses, and Martin sings the bridge (usually Ballard or Ross was given the lead on the group's recordings at that time).  "After All" was also later covered by The Marvelettes, in the early 1970s, with group member Wanda Young Rogers as lead.  (There's a connection to the two previous groups in that Wanda Young was the wife of Miracles member Bobby Rogers, and she was the only member of The Marvelettes on the song—as with the late-1960s singles of The Supremes, The Andantes served as background singers.)  Their version appears on the album "The Return of the Marvelettes", and later became the group's belated final single (it failed to chart). "Could It Be I'm Falling in Love" is a 1972 song recorded by the American R&B vocal group The Spinners (known as "Detroit Spinners" in the UK).  The song was co-written by Melvin and Mervin Steals, two songwriter brothers working for Atlantic, who were sometimes credited as "Mystro and Lyric."  It was produced by Thom Bell, recorded at Philly's Sigma Sound Studios and the house band MFSB provided the backing.  Bobby Smith sings lead through most of the song while Philippé Wynne handles vocal duties on the song's outro. The Miracles (also known as Smokey Robinson and the Miracles from 1965 to 1972) were an American rhythm and blues vocal group that was the first successful recording act for Berry Gordy's Motown Records, and one of the most important and influential groups in pop, rock and roll, and R&B music history.  Formed in 1955 by Smokey Robinson, Warren "Pete" Moore, and Ronnie White, the group started off as the Five Chimes, changing their name to the Matadors two years later.  The group then settled on the Miracles after the inclusion of Claudette Robinson in 1958.  The most notable Miracles line-up included the Robinsons, Moore, White, Bobby Rogers and Marv Tarplin.  After a failed audition with Brunswick Records, the group began working with songwriter Berry Gordy, who helped to produce their first records for the End and Chess labels before establishing Tamla Records in 1959 and signing the Miracles as its first act.  The group eventually scored the label's first million-selling hit record with the 1960 "Grammy Hall of Fame" smash, "Shop Around", and further established themselves as one of Motown's top acts with the hit singles "You've Really Got a Hold on Me", "What's So Good About Goodbye", "Way Over There", "I'll Try Something New", "Mickey's Monkey", "Going to a Go-Go", "(Come 'Round Here) I'm the One You Need", "Just A Mirage", "If You Can Want", "More Love", "I Don't Blame You at All", "Ooo Baby Baby", The multi-award-winning "The Tracks of My Tears", "Special Occasion", "I Second That Emotion", "Baby Baby Don't Cry", the number-one Pop smashes "The Tears of a Clown" and "Love Machine", "Do It Baby", and "My Girl Has Gone",among numerous other hits. "Pure Smokey" is a song by English musician George Harrison, released in 1976 on his debut album for Dark Horse Records, "Thirty Three & 1/3".  The song was the second of Harrison's musical tributes to American soul singer Smokey Robinson, following "Ooh Baby (You Know That I Love You)" in 1975.  Harrison frequently cited Robinson as one of his favourite vocalists and songwriters, and Robinson's group the Miracles had similarly influenced the Beatles during the 1960s.  In the lyrics to "Pure Smokey", Harrison gives thanks for the gift of Robinson's music, while making a statement regarding the importance of expressing appreciation and gratitude, rather than forgetting to do so and later regretting it.  The song title came from the name of Robinson's 1974 album "Pure Smokey". "When Smokey Sings" is a song by English band ABC, released as the first single from their fourth studio album, "Alphabet City" (1987).  The lyrics and title of the song are a tribute to R&B and soul singer Smokey Robinson.  Robinson himself was on the Billboard Hot 100 pop charts with his single "One Heartbeat" at the same time as this tribute song, marking one of the only times to date that a singer simultaneously was the performing artist of one Top 40 hit, while the subject of another chart hit.  For the week ending 3 October 1987, both songs were in the Top 10 simultaneously.  In 1964, the Carefrees hit No. 39 with "We Love You Beatles" during a time when the Beatles had several hits simultaneously in the Top 40. "Way Over There" is a 1960 Motown soul song and single, written by William "Smokey" Robinson, produced by Berry Gordy, and first performed by The Miracles (credited as "The Miracles featuring Bill 'Smokey' Robinson") for the Tamla (Motown) label.  It was one of The Miracles' earliest charting singles, reaching #94 on the "Billboard" Pop chart.  Motown president Berry Gordy, Jr. had The Miracles record the song several times during its chart run.  The first version had minimal orchestration.  The second version added strings, and this is the version played by most oldies stations today.  Claudette (Mrs. Smokey) Robinson had several lead parts on this song (as the "lover way over there on the mountainside"), answering Smokey's leads with chants of "Come to me, Baby".  The song's B-side, "(You Can) Depend on Me", while not charting nationally, did become a popular regional hit in many areas of the country,and Smokey still sings it in his live shows today. "(You Can) Depend on Me" (TAMLA 54028), was a 1959 song by Motown Records group The Miracles, which also appeared on the group's first album, Hi... We're The Miracles (released in 1961).  It also appeared as the "B" side of the group's hit single, "Way Over There."  It was written by Motown Records' President and founder Berry Gordy and Miracles member William "Smokey" Robinson.  While not charting nationally, this song was a very popular regional hit tune in many areas of the country, so much so, in fact, that it was included on the group's first greatest hits album, Greatest Hits from the Beginning, and Smokey still sings it, by request, in his live shows today. Absolutely is a comprehensive greatest hits package by the English band ABC, released in 1990.  This covered all the eras up until 1990, and had all their singles together.  A video package featuring their promos was also released.  One new song called "The Look of Love (1990 Remix)", was also released to promote it, but not with approval of the band.  Other remixes were included on this compilation, including "When Smokey Sings (The Miami Mix)", "Be Near Me (Munich Disco Mix)" and "One Better World" (Pickering-Park Mix).
