Who said peace love and rock n roll?

The slogan "Peace, Love, and Rock 'n' Roll" originated in the mid-1960s as a countercultural phrase popularized by the hippie movement. It symbolized resistance to established power structures, promoting ideals of peace, acceptance, and alternative ways of life centered around rock music. However, its exact origin in terms of individual originators or specific events is challenging to pinpoint, as it emerged collectively from broader cultural conversations and social change initiatives of the era.
