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 was partly based on the raga Darbari Kanada. The waltz-time "Red Lady Too" includes what musicologist Walter Everett describes as "'Moonlight' Sonata-like suspensions on piano, honky-tonk piano, Mellotron, and drums". Ashton performed the tack piano part, with Barham supplying the lower-register piano accompaniment. On "Tabla and Pakavaj", Mahapurush Misra played the two types of hand drums named in the title, the barrel-shaped pakhavaj being another mainstay of Hindustani classical music. "In the Park" includes Sharma's santoor alternating solos with surbahar and tabla tarang. Neither of these last two tracks appears in the film.
