Not sure exactly where the Golden Gate was on Oxford Road Station Approach, but the place has been mentioned by a few people now. 'Edtheball' at the Manchester Forum remembers the Golden Gate as a "class 'A' gaffe. My old man - a Daily Express man - knew all the dodgy clubs, and he said that this one was haunted by an assortment of 'hooks, crooks and comic singers'. And after going in a few times - God, we must have been desperate - I knew what he meant [1]."
