St Andrews' oldest, funniest and - incidentally - only improv comedy troupe are back at the Fringe with their unique mix of sparky, spontaneous and side-splittingly funny short and long improv. Having been cramped up for over a year, Blind Mirth are raring to go and promise wit, charm and, if all else fails, a startling look into what they're like in the bedroom. It may be wacky, inane, and fuelled almost solely on a rather questionable student diet, but it certainly won't be boring. Have your suggestions at the ready!
