I’ve been slightly intrigued and slightly obsessed with Bob Slayer for the last few years. Slayer came to comedy via tour managing rock bands and he has, in his eccentric way, shaken things up a bit. His Heroes venues in Edinburgh threw a spanner in the festival works, straddling the Free Fringe and the paying Fringe by letting people in for nothing but also selling tickets for a fiver to mugs who wanted guaranteed seats. The booking policy seemed to work – he put on Adrienne Truscott, who picked up the Foster’s Panel Prize in 2013.
