Their first minor hit was "I Ain't Gonna Eat Out My Heart Anymore" (1965), followed by the #1 single "Good Lovin'" (1966, originally by the Olympics). Soon, the band began to mature as songwriters and released other hit songs written themselves, including "Groovin'", "It's Wonderful", "How Can I Be Sure?" and "Beautiful Morning". Their best-remembered song was "People Got to Be Free" (1968), a passionate plea for racial tolerance; unusually for their time, the Rascals refused to tour on unintegrated bills. After "People Got to Be Free", the Rascals never regained their former fame or had as large a hit, partially because of the loss of Brigati in 1970, followed by Cornish in 1971.
