Sam and his mum Prunella Scales are the readers for next week's episode of With Great Pleasure, which has readings chosen by Nicholas Parsons.
He will perform at "Stories to make you laugh or cry", a fundraiser organised by First Story, on 29 February.
Sam is the narrator for Britten Films at the Aldeburgh Festival. It will be performed 14 June. Booking opens 6 March.
A picture of Sam wearing the Slanket of Con has been added to the Slanket's gallery.
He was a guest at the recent Northern Stage fundraising dinner (via his Twitter, @exitthelemming).
