Lady Gaga sang a new song At Australian Concert

Lady Gaga sang a new song during her concert in Melbourne, Australia. She told audience, "So this song may or may not be on my next album. I wrote it a little while ago and I've never ever played it for anyone. I'm going to play it because, actually, I've been really excited and impressed with how many super fans have been at every show. I truly feel it would be a disservice to all of you to not play it before I leave." Source
