Zac grinned as he watched and listened, eyes darting between the two musicians. It didn't take him long to pick the song, quickly pulling out his phone and googling the lyrics as he grabbed the nearby mic. He got into the groove of things, banging his he's softly before belting it out with a powerful, passionate voice, emulating the vocal style of Paul Di'Anno. He read through the lyrics once and was good to go, a massive smile on his face the whole time.
