The excitement of returning to enjoy live music was felt by visitors and performers alike, with many taking the time to express their gratitude for being able to return to entertaining their loyal fans following a long lockdown last year.

Although not without its hiccups, with last-minute COVID-related withdrawals from Waterparks and Sum 41, the show went on – and with a bang.
