Sessions for the proposed album took place in London in February 1971. Beatles historian Keith Badman gives dates of 2 and 3 February, while authors Chip Madinger and Mark Easter write that "according to reports", the sessions took place between 8 and 21 February. In addition to playing guitar, Harrison enlisted some of the musicians who had contributed to "All Things Must Pass": Gary Wright, on keyboards; Derek and the Dominos drummer Jim Gordon; Voormann and Carl Radle (the latter another member of the Dominos), alternating on bass; and Badfinger's Pete Ham on second guitar and percussion. Another participant was Leon Russell, who had worked with Spector as a regular member of the Wrecking Crew during the mid 1960s. Badman writes that Lennon participated in the second session at Abbey Road Studios, on 3 February, allegedly playing piano. Ronnie was also at these sessions, having arrived in London the previous day with instructions to come to Abbey Road and rehearse with Harrison, Russell and Ham.
