Regarding the mask. As an artist, you perform for people. Your fans are used to seeing you in a certain way. Freddie Mercury performed this song and it was an incredible success! Freddie died quite young and lately he used a lot of makeup to hide his face, marked by illness. The lyrics of the song also hint at this. Many artists understand this with a "mask" you put on when you perform! This is my own interpretation of why Angelina has this mask before she starts singing. As the lyricist points out "The show must go on". A genius at work. I am so happy for everything Angelina gives me. Open to corrections from any Angels or Queen-fan if I mispoke. / A Swedish Viking.
Angelina can help us all. She can pick us up when we’re down. She can bring us to tears of joy or release when we need it. She can always fill us with love. ❤❤
