A. C. Bhaktivedanta Swami Prabhupada
Paramahansa Yogananda, a Bengali saint was an early proponent of kirtan in the west, chanting Guru Nanak Dev's "Hey Hari Sundara" ("Oh God Beautiful") with 3,000 people at Carnegie Hall in 1923. Kirtan became more common with the spread of Gaudiya Vaishnavism by the International Society for Krishna Consciousness's (ISKCON) founder A. C. Bhaktivedanta Swami Prabhupada in the 1960s.
