You've seen the Hard Rain exhibition, now come and hear Mark Edwards tell how he was inspired after getting lost in the Sahara and being played a tape of Dylan's eponymous song by the Touareg nomad who rescued him. The event is in the RBGE Lecture Theatre from 7pm-8.30pm on Monday 29 October. Tickets costing £3 adult/£2 concessions can be purchased from the Palm House Reception, through the Press & Marketing Office on 0131 248 2900 or at the door on the night.
