Yes! I've not seen the Ferry in there, but i've seen him out and about. A few other well known people shop in there from time to time. I've seen Gilmour in there twice.
I didn't want to trouble Gilmour too much, he was shopping and looked a bit inconspicuous so I just asked for a quick signature...
David Gilmour: he pops occasionally into the Sainsbury's I work in during the evenings...so I plucked up the courage to ask him. Very quiet man.
Michael Palin: Impromptu visit to a book signing of his in Waterstones in Chester.
The Decemberists: signed CD by the Oregon folk troupe. Lovely people.
