Here are 10 more posters from that HK Film Archive calendar. They are from 1966-1967.
And in the theme of that period, here are two songs from Connie Chan. I picked up a CD of her songs from films but most of them are of the Chinese Opera variety which I really can't listen to for long before I reach for the aspirin. These two are more contemporary to the time. No idea what the song titles are or from which film they came. I hope these work as I am away from home and doing this on perhaps the slowest dial-up connection in the world and there is no way for me to test to see if they play correctly.
