The song didn't require Johnny to play very much, except on the chorus, so he did just that, with Jenny picking up the harmonies when needed. Euterpe played that fiddle like the titular devil had possessed her, and it was as mesmerizing to watch now as it had always been.
He caught her gaze when she looked over, and raised his eyebrows in response. He could play the fiddle, along with a slew of other instruments, rather well, but he'd never changed mid-song before. Still. There was a first time for everything, and he wasn't afraid of trying something new to give a crowd a good show.
As he sang the preceding lyrics, he slid his guitar off to the side as he saw the fiddle and the bow leave her hand. He caught it and tucked it under his chin, and started drawing the bow over the strings like he'd been born doing it. For him, this was better than drugs, better than just about anything in the world.
