good harmonica player. At various stages while working on the project, Harrison returned to Twickenham to ensure that each musical piece married up with its scene in the film; he later recalled: "it always worked. It was always right." Final mixing began on 31 January, and a late overdubbing session took place on 11 February, when extra sound effects were added to "Dream Scene". Harrison mixed the recordings with Ken Scott, completing stereo and mono versions of the album. Harrison then went back to India on 15 February, with Lennon and their wives, to study meditation with the Maharishi in Rishikesh. Having been allocated a budget of £600, Harrison eventually spent £15,000 on recording the film soundtrack, paying the difference himself. One of the non-soundtrack pieces taped at the end of the Bombay sessions was "The Inner Light", which he completed at Abbey Road in early February. This song became the first Harrison composition to appear on a Beatles single when it was issued as the B-side to "Lady Madonna" in March 1968, a release that served to cover the band's absence in Rishikesh. The Remo Four song "In the First Place" was another product of the Wonderwall sessions, although the track remained unreleased until the late 1990s. In 1993, Harrison told Simpsons creator Matt Groening that Wonderwall Music had been his most enjoyable album to make. Musical content The nineteen tracks on Wonderwall Music range from just over a minute in length to five-and-a-half minutes. On some pressings of the 1968 LP, various pieces lacked mastering rills between them; with these selections instead presented as medleys, the number of distinct album tracks was reduced to twelve. On many of the Indian selections, instruments such as sitar, surbahar and harmonium provide a drone-like backing, over which Harrison's chosen instrument plays the main musical theme. In the original album credits, Harrison was listed as producer, writer and arranger but was not included among the performers, leading to an assumption that he did not play on the recordings. After consulting Barham in 2002 for his book While My Guitar Gently Weeps, Leng credited Harrison as a performing musician, and Spizer also recognised him in his track-by-track list, published in 2005. The performer credits in the 2014 reissue of Wonderwall Music rectified the situation, and list Harrison on piano and guitar. Side one The album opens with "Microbes", which consists of call-and-response shehnai
