"Groovin'" is a song written by American singer-songwriters Felix Cavaliere and Eddie Brigati, initially recorded by their group the Young Rascals in 1967. Cavaliere was inspired to compose the song by his girlfriend Adrienne Buccheri, whom he only got to meet on Sundays amidst heavy touring and recording. Musically, the song differs from most of the band's previous output, leaving the garage rock genre for Latin American influences, such as baião. Lyrically, "Groovin'" tells the tale of a narrator spending time with his partner on a Sunday afternoon. The song was arranged and recorded at the Talentmasters Studios, New York City in March of 1967.
