Tony Blackburn will be standing in for Judi Spiers on BBC Radio Devon for three days next week.
And the following week, Pat Sharp will be covering the same show between 9am and midday. Pat was most recently hosting drive time on Heart Cambridge.
Mark Grinnell, Editor of BBC Radio Devon, said: "Tony and Pat are true broadcasting legends and share a passion for life and brilliant music with everyone here. They are looking forward to joining the Radio Devon family temporarily and we can assure them of a warm welcome and maybe a Devon Cream Tea."
