Brian May and Professor Roger Taylor, Doctors' shows at the Fringe, Rachel Parris

Queen guitarist Brian May fell in love with 3D photography as a child and has since gone on to establish his own publishing company devoted to sharing stereoscopic work from the Victorian era to the present day. May's latest publication is a book by Professor Roger Taylor about the Scottish photography pioneer George Washington Wilson. May and Taylor discuss why Wilson's 3D photographs of Scottish landscapes and street scenes remain as captivating today as they were during the 3D boom of the 1850s and 60s.

As the NHS celebrates its 70th anniversary, three doctors are performing their own stand up shows on the Festival fringe. Adam Kay, Dr Kevin Jones and Kwame Asante talk to Kirsty about using their working lives as material.
