Is there any footage of when this happened? I seriously doubt it, but if there is, I'd love to see it. I actually asked this question on an old topic, but it isn't showing...

"Once, during an early soundcheck, Freddie got mad at the rest of the band over something and stalked out, saying he was leaving for good. When he didn't return after about half an hour, Roger and Deaky were panicking, certain he'd made good on his threat. Brian, however, calmly picked up the microphone Freddie had discarded and called into it, "Oh, Freddie? Freddie-poo? Freddiekins, where are you?" A moment later Freddie poked his head back in to yell "Don't call me that!" Brian just smiled and said, "I knew that would get you back in here."
