When Mukunda Goswami interview George Harrison in 1982, the later reminisced:
“Before meeting Prabhupada and all of you, I had bought that album Prabhupada did in New York, and John and I listened to it. I remember we sang it for days, John and I, with ukulele banjos, sailing through the Greek Islands chanting Hare Krishna. Like six hours we sang, because we couldn’t stop once we got going. As soon as we stopped, it was like the lights went out. It went on to the point where our jaws were aching, singing the mantra over and over and over and over and over. We felt exalted; it was a very happy time for us.”
From his time with The Beatles, George Harrison remained an ardent follower of the Hare Krishna movement till his death. His meeting with Srila Prabhupada in September 1969 was a vital point in his life as he was introduced to Krishna Consciousness. He produced the Radha Krsna Temple Album in 1971, the most popular song in it being the Hare Krishna Mantra Single

I am an ardent follower of The Beatles. It is not very well know about hoe George Harrison was so much influenced by the Indian culture especially by Srila Prabhupada.
