Sylvester McCoy as The Doctor and Sophie Aldred as Ace during studio camera rehearsals on the set of the Doctor Who story 'Ghost Light'.

You can see that during rehearsals Sylvester wore his glasses.

'Ghost Light' was the last story of the classic series to be recorded. Knowing that the series wasn't being renewed, John Nathan-Turner kindly allowed me to take photographs during studio rehearsals, very unusual in those days.
