The four-piece a cappella group from Finland return. Fork’s look and repertoire is much more glam rock than Glee, with one member being labelled as the ‘Legolas from hell’. They have an ever so slightly intimidating presence, but this only adds to their wacky performance.

Clad head to toe in black leather and PVC, the group make their way through a number of popular songs including hits by Lady Gaga, Queen and Muse; as well as a number from their homeland. Their live vocals are combined with loops and echoes, which means the lack of a band or backing track goes completely unmissed.

What was very noticeable was the audience’s enjoyment; the crowd needed barely any encouragement to get up on their feet and dance. The only aspect that could have been improved on was the song choices, as for every singalong hit there was another that did not work as well. However, the presence and energy that Fork bring to the stage cannot be doubted.

Assembly George Square, 226 0000, until Sun 26 Aug, 10.25pm, £14–£15 (£11–£12).
