"Goin' Out of My Head" is a song written by Teddy Randazzo and Bobby Weinstein, initially recorded by Little Anthony & the Imperials in 1964. Randazzo, a childhood friend of the group, wrote the song especially for them, having also supplied the group with their previous Top 20 Hit "I'm on the Outside (Looking In)". Their original version of the song was a Billboard Top 10 Pop hit, reaching #6 on the Billboard Hot 100, and #1 in the Canadian RPM-list in 1965. The song peaked at #8 on Cashbox magazine's R&B chart (Billboard was in a chart recess for R&B listings at that time). The Little Anthony & the Imperials original recording is the most commonly known version of the song, and the definitive version, although it's since been covered by many other artists.
