Mikey flushed, ducking his head. "Right, okay. Muggle band, very important." He couldn't help a small grin as he peered back up at Z. "Should I conjure up quill and parchment so I can take notes?" He wasn't even entirely joking. He had no idea how one went about picking up Muggle radio broadcasts or which of their shops stocked music. If he was going to listen to new things - and he was interested in doing so - he was definitely going to need some pointers.
"How do you know this stuff, anyway?" he asked curiously. It was on the tip of his tongue to ask Z if she was Muggleborn, but it seemed an impertinent sort of question. Plus knowing his luck, if he did, it would turn out she was from one of those families that found a question like that insulting and answered it by setting bats on you.
