"Mickey's Monkey" is an 1963 song recorded by the R&B group The Miracles on Motown Records' Tamla label.
 It was written and produced by Motown's main songwriting team of Brian Holland, Lamont Dozier, and Eddie Holland, who later went on to write 2 more Miracles hit singles, the Top 40 "I Gotta Dance to Keep From Crying", and the Top 20 "(Come 'Round Here) I'm The One You Need".
 This was unusual, as most Miracles songs were composed by the group members themselves.
The Marvelettes was an American girl group that achieved popularity in the early- to mid-1960s.
 They consisted of schoolmates Gladys Horton, Katherine Anderson (now Schaffner), Georgeanna Tillman (later Gordon), Juanita Cowart (now Cowart Motley), and Georgia Dobbins, who was replaced by Wanda Young (now Rogers) prior to the group signing their first deal.
 They were the first major successful act of Motown Records after the Miracles and its first significantly successful girl group after the release of the 1961 number-one single, "Please Mr. Postman", one of the first number-one singles recorded by an all-female vocal group and the first by a Motown recording act.
The Originals, often called "Motown's best-kept secret", were a successful Motown R&B and soul group during the late 1960s and the 1970s, most notable for the hits "Baby, I'm For Real", "The Bells" and the disco classic "Down To Love Town".
 Formed in 1966, the group originally consisted of bass singer Freddie Gorman, baritone (and the group's founder) Walter Gaines, and tenors C. P. Spencer and Hank Dixon (and briefly Joe Stubbs).
 Ty Hunter replaced Spencer when he left to go solo in the early 1970s.
 They had all previously sung in other Detroit groups, Spencer having been an original member of The (Detroit) Spinners and Hunter having sung with The Supremes member Scherrie Payne in the group Glass House.
 Spencer, Gaines, Hunter, and Dixon (at one time or another) were also members of The Voice Masters.
 As a member of the Holland–Dozier–Gorman writing-production team (before Holland–Dozier–Holland), Gorman (as a mailman) was one of the co-writers of Motown's first number 1 pop hit "Please Mr. Postman", recorded by The Marvelettes.
 In 1964 The Beatles released their version and in 1975 The Carpenters took it to number 1 again.
 This was the second time in pop history that a song had reached number 1 twice as "The Twist" by Chubby Checker, reached number 1 in both 1960 and 1961.
 In 2006, "Please Mr. Postman" was inducted into the Songwriters Hall of Fame.
"Playboy" is a song composed by Brian Holland, Robert Bateman, Mickey Stevenson and singer Gladys Horton, lead vocalist of the Motown singing group The Marvelettes, who recorded the song and released it as a single on Motown's Tamla imprint in 1962.
 The single, led by Horton, is about a man who fools around with a lot of women and the woman who narrates the story warns him to stay away from her due to the stories she heard of him "running around with every woman in town".
 Horton is helped out in the song by her Marvelettes cohorts Wanda Young, Georgeanna Tillman, Katherine Anderson & Juanita Cowart.
 This was released as the third single by the Marvelettes and was their second top ten pop hit reaching number seven on the charts while reaching number four on the R&B chart.
I Like It Like That is an album by Motown group the Miracles, compiled for the UK market and released on the UK Tamla-Motown label (TML11003) as one of its initial group of six albums in March 1965 (there was no equivalent album to this in the USA).
 Known as the Miracles' "forgotten album", few people, outside of Motown insiders, hard-core Miracles fans, and collectors, remember that it had even existed.
 This album featured a combination of several new-for-1964 songs along with previously-issued material from the group's album from the year before, "The Miracles Doin' Mickey's Monkey".
 New for 1964 songs included "I Like It Like That" (the Top 30 title song), the Bobby Rogers-led flip side "You're So Fine and Sweet,"(this is the "only" original Miracles studio album that has that song), "That's What Love Is Made Of" (another 1964 hit) that the group performed on the American International Pictures release, the T.A.M.I. Show that year, and "Would I Love You", a song that became a popular regional hit tune for the group in Pennsylvania and The Midwest.
 The album also featured a Claudette Robinson-led cover version of the Orlons' #2 Pop smash, "The Wah Watusi".
 (Claudette is also featured with the rest of the group on the album's cover), and the group's 1963 Top 40 Hit, "I Gotta Dance to Keep From Crying".
 Several of the group's other 1964 songs, including the chart hits "(You Can't Let the Boy Overpower) The Man in You", "Come On Do the Jerk", and its "B" side, "Baby Don't You Go", were not included.
 The new 1964 recordings "I Like It Like That", "Would I love You" and "That's What Love Is Made Of" were included on the only US Miracles 1964 album release "Miracles Greatest Hits From The Beginning" which was the first double album released by Motown Records.
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.
"I Want a Guy" is a song written by Freddie Gorman, Berry Gordy and Brian Holland and was the debuting single for Motown girl group The Supremes in 1961.
 It was also recorded by The Marvelettes.
 Featuring Diana Ross, going by her given name, Diane Ross, in lead, the song was a doo-wop ballad similar to what the Supremes had been recording since forming as "The Primettes" two years earlier.
Please Mr. Postman is the 1961 studio debut album from Motown girl group The Marvelettes and the sixth album ever released by the company.
 The focal track is the number-one hit single, "Please Mr. Postman".
 The album notably features cover versions of label mates The Miracles' "Way Over There and "I Want a Guy", which was the debut single for fellow Motown girl group The Supremes the same year, and their cover had served as the b-side to "Twistin' Postman" the less successful follow-up to "Please Mr. Postman."
 Although the original version by The Supremes flopped, The Marvelettes' cover became a regional hit.
"Please Mr. Postman" is a song written by Georgia Dobbins, William Garrett, Freddie Gorman, Brian Holland, and Robert Bateman.
 It is the debut single by the Marvelettes for the Tamla (Motown) label, notable as the first Motown song to reach the number-one position on the "Billboard" Hot 100 pop singles chart.
 The single achieved this position in late 1961; it hit number one on the R&B chart as well.
 "Please Mr. Postman" became a number-one hit again in early 1975 when the Carpenters' cover of the song reached the top position of the "Billboard" Hot 100.
 "Please Mr. Postman" has been covered several times, including a 1963 version by the English rock group The Beatles.
"Bad Girl" is a 1959 doo-wop single by The Miracles.
 Issued locally on the Motown Records label, it was licensed to and issued nationally by Chess Records because the fledgling Motown Record Corporation did not, at that time, have national distribution.
 It was the first single released (and the only one released by this group) on the Motown label - all previous singles from the company (and all following ones from the group) were released on Motown's Tamla label.
 Although The Miracles had charted regionally and on the R&B charts with several earlier songs, including "Got a Job", "I Cry", "I Need a Change", and "(You Can) Depend on Me", "Bad Girl" was their first "national" chart hit, reaching #93 on the "Billboard" Hot 100.
 Written by Miracles lead singer Smokey Robinson and Motown Records' President and Founder Berry Gordy, "Bad Girl" is a sad, remorseful ballad about a young woman, whom Robinson, as the narrator, says "was so good at the start", but who later in the song "is breaking my heart".
 It is in the popular doo-wop style, as several of The Miracles' songs were during the late 1950s.
 The record's success, coupled with the distributor's failure to pay Gordy and The Miracles properly for its sales, prompted Robinson to urge Gordy to "go national" with it, meaning that Motown should do its own national distribution of its songs, and eliminate the middleman, to ensure that all money from sales of its records would go directly to the label.
