This was the opening night of their tour wherein they played their debut album in full (plus an encore of three other songs).
I believe there was meant to be a support act, but for reasons unknown they were unable to play.
It was one of many tours under the 'Revive Live' banner which was a collaboration between the MVT and National Lottery which offered a 'buy one, get one free' ticket option to try and get people back into venues as the Covid pandemic hopefully began to scale back its impact on live music.
