Between 5 and 6 April 1965, while filming the second Beatles film, "Help!", at Twickenham Film Studios, George Harrison first encountered a sitar, the Indian string instrument that would be a prominent feature in "Norwegian Wood". It was one of several instruments being played by a group of Indian musicians in a scene set in an Indian restaurant. "Norwegian Wood" was not the first Western pop song in which an Indian influence was evident: the raga-like drone was found in the Beatles' "Ticket to Ride", as well as in the Kinks' song "See My Friends". The Yardbirds also created a similar sound with a distorted electric guitar on "Heart Full of Soul". Barry Fantoni, a friend of Ray Davies of the Kinks, said that the Beatles first got the idea to use Indian instrumentation when Fantoni played them "See My Friends". According to author Ian MacDonald, however, while the Kinks' single most likely influenced the Beatles, Davies could well have been influenced by "Ticket to Ride" when recording "See My Friends". Rather than the Kinks or the Yardbirds, Harrison attributed his growing interest in Indian sounds to people mentioning the name of Indian sitarist Ravi Shankar to him, culminating in a discussion he had with David Crosby of the Byrds. The discussion took place in Los Angeles on 25 August, during the Beatles' 1965 American tour. Once back in London, Harrison followed Crosby's suggestion by seeking out Shankar's recordings, and he also purchased a cheap sitar, from the Indiacraft store on Oxford Street. Ringo Starr later cited Harrison's use of sitar on "Norwegian Wood" as an example of the Beatles' eagerness to incorporate new sounds in 1965, saying: "you could walk in with an elephant, as long as it was going to make a musical note."
