The Young Rascals hit the top of the Billboard Hot 100 chart with their single “Groovin’” on May 20, 1967. The track was released off the band’s third album of the same name and featured the B-side "Sueño.”When “Groovin’” hit number one, it claimed the top spot from "The Happening" by the Supremes. They held on for two weeks in the top spot before "Respect" by Aretha Franklin moved up to number one. They later hit the top again the following month.The track was inspired by time spent on a Sunday afternoon off with loved ones:“If you look at the story line, it's very simple: we're groovin' on a Sunday afternoon because Friday and Saturdays are when musicians work. The simplicity of it is that Sundays you could be with your loved one,” band member Felix Cavaliere told interviewer Seth Swirsky in an outtake from the documentary “The Beatles Story.”
