The Beacon Theater shows in NYC made Queen "our band". To thiis day, they remain one of the best live performances I saw come through NYC as a kid - and I saw them ALL.
One vivid recollection - during each show Freddie flipped a deck of cards towards the audience during one of the later songs in the set. He flipped the cards in the air, littering the stage, where they were in short order joined by rose petals and assorted props and forgotten. On the last night of the five shows, I went down to the front of the stage where I saw the cards up close - there were about 20 or so littering the stage - each card was the Queen of Hearts.
I don't think this was the usual thing for Fred to do......maybe he done it once at one of these shows, but there is no other evidence that this actually happened.
