Admittedly I only heard of Bronski Beat a few years ago and I've never heard of the other artist or song until just listening. Don't care for either song but voted for STB as its the era and sound i like more. Some stuff from the 70s i just can't get into and don't want to try.
The video for STB seems pretty progressive for the early 80's. I was too young to recall how Americans even took to George Michael in his heyday, but the British seem to have been more open to openly gay themes and artists in that time.
