The contributing musicians included Indian sarodya Aashish Khan and tablist Mahapurush Misra, the last of whom was the regular accompanist to Khan's father, Ali Akbar Khan. Aashish Khan and Misra's contributions were recorded at Abbey Road, rather than later in India, since the pair were performing in London in December 1967. Barham attended this session and also contributed to some of the Western recordings for "Wonderwall", playing piano, harmonium and flugelhorn, and providing orchestral arrangements for flutes, oboes and trumpet. Another session with some unnamed Indian musicians took place on 5 January 1968.
