At this point, I'm sure you've heard this song a lot this year. This can be the last time, if you want. But it seemed fitting, in a year when we've needed everyday heroes, in a year without a superhero movie, this song seems to provide an appropriate coda.
Or you can go to Totally Covered and check out the "Heroes" special.
Not really a hit in 1977, when it was released, it DID become a worldwide hit on its posthumous rerelease in 2016. It is seen as an inspiration for the reunification of Germany - that's how powerful a song this is. His June 1987 performance in Berlin, featuring this song broadcast to both sides of the Berlin Wall, is seen as an early catalyst for these unification efforts, as music lovers on both sides of the wall enjoyed the concert live, together.
I was lucky enough to see David Bowie perform this song live in 1991, on what he billed as a farewell tour to his old songs (of course, it wasn't - those songs were amazing). Here he is in 1987 - the same tour as the one in Berlin (although not his Berlin performance).
