Internationally renowned a cappella sensation Semi-Toned returns to the Edinburgh Fringe for its sixth consecutive year.

Performing music from across the ages with their signature comic twist, this show is sure to thrill audiences of all ages. 'If there's a seat to be had, grab it!' ***** (BroadwayBaby.com, 2017).
