Calvin Street Liverpool - I lived there in, I think it must have been 1980 - it had been renamed at sometime, I can't remember if it was from Burdett Street to Calvin or the other way around. There was a three story block of walk up flats and opposite a relatively modern block. It has all gone now to be replaced by modern houses. I actually went for a walk around there the other week, but I was unable to locate it as the streets have change so much. However, I don't think it was far from Sylvester Street.
