Originally written and recorded with three verses, the retitled "Hang On Sloopy" was edited down to two verses for the single and resulting Hang On Sloopy album. The unedited three-verse version, at 3 minutes, 50 seconds, first appeared on the 1970 Bang various artists compilation Bang & Shout Super Hits (BLPS-220), then again on the 1991 Rhino Records various artists compilation Grandson of Frat Rock! Vol. 3 and the 1995 Legacy Recordings compilation Hang On Sloopy: The Best of the McCoys. Legacy The Yardbirds In 1964, Eric Clapton, who was then lead guitarist for the Yardbirds, introduced the group to the Vibration's "My Girl Sloopy". Before they could record the tune, however, Clapton left the group. During his second recording session on April 13, 1965, with the Yardbirds, new guitarist Jeff Beck and the group recorded the song at the Advision Studios in London. Their 5:36 rendition was considered unusual for a studio recording at the time; AllMusic's Bruce Eder called it "the first extended jam to emerge on record from a band on the British blues scene". Group chronicler Greg Russo also commented on the group's "humorous take [in which they] used out of control vocal buildups", which was part of their live performances, such as at the fifth Richmond National Jazz and Blues Festival on August 6. When looking for material for the Yardbirds' first American album, manager Giorgio Gomelsky included "My Girl Sloopy" and two other tracks recorded at Advision with Beck. The hastily produced album was released on July 5, 1965, to generate interest for the group's upcoming first US tour. On August 11, the three songs formed the Yardbirds' first extended play (EP) release in the UK, where it reached number two on the record chart. Other charting versions Little Caesar and the Consuls released a version of the song in 1965 that reached No. 50 on the Billboard pop chart and No. 3 in Canada. The Ramsey Lewis Trio recorded the song for their 1965 live album Hang On Ramsey!; it reached No. 6 on the US R&B chart, No. 11 on the US pop chart, No. 18 on the US adult contemporary chart, and No. 37 in Canada. "Es Lupe", a Spanish-language cover version by Los Johnny Jets, was released in 1965. It topped the Mexican charts for 13 weeks. Leno e Lílian, a Brazilian vocal duo, released a cover version in Portuguese
