Thunderous applause, a real buzz and the feeling of having just witnessed something very special - that is what I remember from seeing Good Vibrations back in 2018.
Five years on since the show's debut at Belfast's Lyric Theatre and it's revival is set to make waves at the city's Grand Opera House before heading to New York.
Ahead of the cast taking to the stage on Wednesday, I sat trying to scramble my recollections of the show from that night, but the overarching memory was the feeling it left me with. Belfast's punk spirit and the true heart of the city that kept on beating through the Troubles.
