Song facts: Dear Prudence
On August 28th 1968, the Beatles recorded Dear Prudence at Trident Studios, London. John Lennon wrote the song about Mia Farrow's sister Prudence while the Beatles were on retreat in India, 1968. Ringo Starr wasn't present for the recording, having quit the band on August 22nd.
Mia Farrow and her sister Prudence joined the Beatles when they traveled to India in February of 1968, along with Mike Love of the Beach Boys and Scottish folk troubadour Donovan Leitch. They were there to study transcendental meditation under the tutelage of Maharishi Mahesh Yogi.
Prudence Farrow got into the meditation in a big way, locking herself away in her room for days at a time. The others were worried about her seclusion and this is what inspired John to write Dear Prudence.
Donovan reportedly helped John with the fingerpicking style of Dear Prudence; which was released on the Beatles' White Album on November 22nd, 1968.
