Jonathan loves music just as much as he loves theatre. He told The Standard in February 2018 that his love for music was likely influenced by his church growing up, which was in the village of Benson in South Oxfordshire, England. "We used to go to church and, musically, I remember that being a massive influence," he said. "It had a band so it was very upbeat and semi-happy-clappy. It made me who I am."
The church also gave him a sense of community, which is something he also values still today. "I have that strong instinct for community and I feel it very heavily when I see it break down," he added. "I worry that people are being pushed more and more into their own heads and it's become about looking after number one. For me, that's a modern-day horror story."
