Delia had an exploratory encounter with Brian Jones.
Brian Jones did [come to the Workshop] - golly! There we were with our hand tuned oscillators and he went into it with his frilly cuffs and things as though he could play it as a musical instrument! He died very young and I cried buckets.
Sonic Boom: Didn't Brian Jones come and visit you one day in the Workshop as well?
Delia: Oh yes, the late Brian Jones. [...] I cried into my washing-up when I heard he'd died.
