I went through a whole Australia tour calling my promoter Dave and on the last day, someone was like, ‘Hey, Nick!’ And I was like, what…? And then, you know when you like try and cover it up and like, you’re there having a conversation and be like, ‘Ah, Nick, yeah it’s really cool to hang out, yeah Nick, it’s all good Nick,’ like overcompensating. But literally for a whole tour he didn’t correct me! Like I called him Dave once and he never corrected me, so he was from then on Dave.
