I just heard that this morning on the radio. I don't know why but aside from the Beatles starring, for some reason, I remember Spinetti's name as being in the cast of Hard Day's Night. I wasn't sure until I clicked the link and saw the picture if I was thinking of the right person. I was. Anyway, that really is where I remember him from.
Sorry to hear of his passing.
