How's this for devotion to your art? Actor/comedian Thom Tuck (Penny Dreadfuls, Horrible Histories, Play What I Wrote) first performed Scaramouche Jones at the Fringe 20 years ago. Then he did it again 10 years ago. After this run he plans to keep doing it every decade until he is 100 – the same age veteran clown Jones is at the start of Justin Butcher's poignant and funny play when we see him alone backstage celebrating his birthday on New Year's Eve 1999.
