Remembering this performance was almost 40 years ago and laughing at comments below: " John Deacon always looks like he's just walking through the Home Depot looking for paint". "Superman wears a Freddie Mercury t-shirt".
My mum forced me to play her some ABBA, her favorite band growing up. She requested Money, Money, Money, which she said was her favorite. Then I played her some of my favorites from the band (no thanks to her influence during my childhood), and we ended up with a small ABBAthon including Gimme! Gimme! Gimme! (A Man After Midnight) and Does Your Mother Know, both of which I like because of their faster beats.
