Robert Wyatt had said that the musicians would ask "What key is that in, Syd?", to which Barrett would simply reply "Yeah" or "That's funny". During this time, Barrett also played guitar on the sessions for Soft Machine founder Kevin Ayers' debut LP, "Joy of a Toy", although his performance on "Religious Experience" was not released until the album was reissued in 2003. The next day's session had Barrett adding backwards guitar to "No Good Trying", and lead to "Terrapin" and "No Man's Land". It was around this time that Jones' involvement came to an end – during these last few sessions, Gilmour had started taking an interest in how Barrett was getting along with his album. Although Barrett had told his flatmate that he was going off "for an afternoon drive", he instead followed Pink Floyd out to Ibiza. During the trip, he asked David Gilmour for his help on the album, and, at the end of May, Malcolm Jones abandoned his production responsibilities.
